+	bison.

+	asn1_get_object_id_der: enhance the range of decoded OIDs
+	The function would only successfully decode OIDs that started
+	with a single octet. This fixes that limitation.
+
+	Resolves: #25
+
+2020-01-11  Nikos Mavrogiannopoulos  <nmav@gnutls.org>
+
+	asn1_decode_simple_ber: added support for constructed definite octet string
+	This allows to decode the whole set of BER encodings for
+	OCTET STRINGs.
+
+	_asn1_decode_simple_ber: allow empty fields
+	Allow empty subcomponents of BER OCTET STRINGS. These
+	are not prohibited by BER.
+
+	asn1_der_decoding2: force the right tag on DER
+	When decoding an OCTET STRING ensure that the right
+	tag is present when strict DER is specified.
+
+	asn1_der_decoding2: fix flag checking
+
+	lib: append: cleanup
+	This simplifies the use of the append() function and
+	fixes the error code on failure.

+
+	Add gtk-doc-strings for compat #defines and ASN1_VERSION:
+
+	Make existing comments parseable by gtk-doc
+
+	gtk-doc: Add long and short project descriptions
+
+	Sync function declarations in header and .c
+	The public header and the .c file need to use not only the same
+	argument types but also the same argument identifiers. Otherwise
+	gtk-doc fails.
+
+	gtk-doc: Fix typo in function description identifier.
+
+	Drop base indent (2 spaces) for gtk-doc compatibility
+	gtkdoc-scan expects struct definitions to start at the start
+	of the line.
+
+	Use .xml filename for gtk-doc
+	gtk-doc uses a .xml instead of .sgml filename by default nowadays.
+
+	Update gtk-doc files
+	Update gtk-doc infrastructure from gtk-doc-tools 1.28.
+	Drop superfluous file. Since gtk-doc >= 1.25 generates
+	xml/gtkdocentities.ent there is no need to export the package version to
+	xml from ./configure.

+	asn1_find_node: added safety check on asn1_find_node()
+	This prevents a stack overflow in asn1_find_node() which
+	is triggered by too long variable names in the definitions

+	pass a too long 'name' constant to asn1_write_value()
+	and friends.  Reported by Jakub Jirasek.

+
+	asn1Decoding: allow decoding with ASN1_DECODE_FLAG_ALLOW_INCORRECT_TIME flag
+
+	decoding: added flag ASN1_DECODE_FLAG_ALLOW_INCORRECT_TIME
+	This flag allows decoding errors in time fields even when

+	even though strict DER adherence is enforced in other fields.
+

+
+	updated gnulib
+
+	Bring in par valgrind and asan tests
+	Ensure that exit code on failure is something different

+- Restore handling of SIZE nodes, thanks to Dmitry Baryshkov.
+- Fix memory leak caught by oss-fuzz, thanks to Dmitry Baryshkov.
+- Gtk-doc fixes, thanks to Dmitry Baryshkov.

+- asn1_get_object_id_der: enhance the range of decoded OIDs (#25).
+  This also makes OID encoding and decoding more strict on invalid

+- The generated tree no longer contains ASN.1 built-in types even

+- Several fixes in ASN.1 definition parser, preventing several

+- Switched to semantic versioning.

+# Libtasn1 README -- Introduction information
+
+This is GNU Libtasn1, a small ASN.1 library.
+
+The C library (libtasn1.*) is licensed under the GNU Lesser General
+Public License version 2.1 or later.  See the file COPYING.LIB.
+
+The command line tool, self tests, examples, and other auxilliary
+files, are licensed under the GNU General Public License version 3.0
+or later.  See the file COPYING.
+
+## Building the library
+
+We require several tools to build the software, including:
+
+* [Make](https://www.gnu.org/software/make/)
+* [Automake](https://www.gnu.org/software/automake/) (use 1.11.3 or later)
+* [Autoconf](https://www.gnu.org/software/autoconf/)
+* [Libtool](https://www.gnu.org/software/libtool/)
+* [Texinfo](https://www.gnu.org/software/texinfo/)
+* [help2man](http://www.gnu.org/software/help2man/)
+* [Tar](https://www.gnu.org/software/tar/)
+* [Gzip](https://www.gnu.org/software/gzip/)
+* [bison](https://www.gnu.org/software/bison/)
+* [Texlive & epsf](https://www.tug.org/texlive/) (for PDF manual)
+* [GTK-DOC](https://www.gtk.org/gtk-doc/) (for API manual)
+* [Git](https://git-scm.com/)
+* [libabigail](https://pagure.io/libabigail/) (for abi comparison in make dist)
+* [Valgrind](https://valgrind.org/) (optional)
+
+The required software is typically distributed with your operating
+system, and the instructions for installing them differ.  Here are
+some hints:
+
+Debian/Ubuntu:
+```
+sudo apt-get install make git autoconf automake libtool bison
+sudo apt-get install texinfo help2man gtk-doc-tools valgrind abigail-tools
+```
+
+PDF manual - Debian <= stretch:
+```
+sudo apt-get install texlive-generic-recommended texlive texlive-extra-utils
+```
+
+PDF manual - Debian >= buster:
+```
+sudo apt-get install texlive-plain-generic texlive texlive-extra-utils
+```
+
+The next step is to run autoreconf, ./configure, etc:
+
+```
+$ ./bootstrap
+```
+
+Then build the project normally:
+
+```
+$ ./configure
+$ make check
+```
+
+Happy hacking!

+# On such systems, the usual invocation of an executable through execlp()
+# or execvp() fails with ENOEXEC if it is a script that does not start
+# with a #! line.  The script interpreter mentioned in the #! line has
+# to be /bin/sh, because on GuixSD systems that is the only program that
+# has a fixed file name.  The second line is essential for perl and is
+# also useful for editing this file in Emacs.  The next two lines below
+# are valid code in both sh and perl.  When executed by sh, they re-execute
+# the script through the perl program found in $PATH.  The '-x' option
+# is essential as well; without it, perl would re-execute the script
+# through /bin/sh.  When executed by perl, the next two lines are a no-op.

+Usage: $ME [OPTION...] VERSION RELEASE_TYPE
+
+Run this script from top_srcdir to perform the final pre-release NEWS
+update in which the date, release-type and version string are
+recorded.  Commit that result with a log entry marking the release,
+and apply a signed tag.  Run it from your project's top-level
+directory.
+
+Requirements:
+- you use git for version-control
+- a version-controlled .prev-version file
+- a NEWS file, with line 3 identical to this:
+$noteworthy_stub
+
+Options:
+  --branch=BRANCH     set release branch (default: $branch)
+  -C, --builddir=DIR  location of (configured) Makefile (default: $builddir)
+  --help              print this help, then exit
+  --version           print version number, then exit
+
+EXAMPLE:
+To update NEWS and tag the beta 8.1 release of coreutils, I would run this:
+
+  $ME 8.1 beta
+
+Report bugs and patches to <bug-gnulib@gnu.org>.

+
+Options:
+  --email ADR use ADR as contact in generated web pages; always give this.
+
+  -s SRCFILE   read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
+  -o OUTDIR    write files into OUTDIR, instead of manual/.
+  -I DIR       append DIR to the Texinfo search path.
+  --common ARG pass ARG in all invocations.
+  --html ARG   pass ARG to makeinfo or texi2html for HTML targets,
+                 instead of '$htmlarg'.
+  --info ARG   pass ARG to makeinfo for Info, instead of --no-split.

+  --no-html    skip generating the html output.
+  --no-info    skip generating the info output.
+  --no-tex     skip generating the dvi and pdf output.
+  --source ARG include ARG in tar archive of sources.
+  --split HOW  make split HTML by node, section, chapter; default node.
+  --tex ARG    pass ARG to texi2dvi for DVI and PDF, instead of -t @finalout.
+
+  --texi2html  use texi2html to make HTML target, with all split versions.
+  --docbook    convert through DocBook too (xml, txt, html, pdf).

+  --help       display this help and exit successfully.
+  --version    display version information and exit successfully.
+
+Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
+
+Typical sequence:
+  cd PACKAGESOURCE/doc
+  wget \"$scripturl\"
+  wget \"$templateurl\"
+  $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default;
+use -o OUTDIR to override).  Move all the new files into your web CVS
+tree, as explained in the Web Pages node of maintain.texi.
+
+Please use the --email ADDRESS option so your own bug-reporting
+address will be used in the generated HTML pages.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file.  It should include the name of the package being
+documented.  manual/index.html is created by substitution from the file
+$GENDOCS_TEMPLATE_DIR/gendocs_template.  (Feel free to modify the
+generic template for your own purposes.)
+
+If you have several manuals, you'll need to run this script several
+times with different MANUAL values, specifying a different output
+directory with -o each time.  Then write (by hand) an overall index.html
+with links to them all.
+
+If a manual's Texinfo sources are spread across several directories,
+first copy or symlink all Texinfo sources into a single directory.
+(Part of the script's work is to make a tar.gz of the sources.)
+
+As implied above, by default monolithic Info files are generated.
+If you want split Info, or other Info options, use --info to override.
+
+You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML,
+and PERL to control the programs that get executed, and
+GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
+looked for.  With --docbook, the environment variables DOCBOOK2HTML,
+DOCBOOK2PDF, and DOCBOOK2TXT are also consulted.
+
+By default, makeinfo and texi2dvi are run in the default (English)
+locale, since that's the language of most Texinfo manuals.  If you
+happen to have a non-English manual and non-English web site, see the
+SETLANG setting in the source.
+
+Email bug reports or enhancement requests to bug-gnulib@gnu.org.

+# This script is derived from GIT-VERSION-GEN from GIT: https://git-scm.com/.
+# It may be run two ways:
+# - from a git repository in which the "git describe" command below
+#   produces useful output (thus requiring at least one signed tag)
+# - from a non-git-repo directory containing a .tarball-version file, which
+#   presumes this script is invoked like "./git-version-gen .tarball-version".
+
+# In order to use intra-version strings in your project, you will need two
+# separate generated version string files:
+#
+# .tarball-version - present only in a distribution tarball, and not in
+#   a checked-out repository.  Created with contents that were learned at
+#   the last time autoconf was run, and used by git-version-gen.  Must not
+#   be present in either $(srcdir) or $(builddir) for git-version-gen to
+#   give accurate answers during normal development with a checked out tree,
+#   but must be present in a tarball when there is no version control system.
+#   Therefore, it cannot be used in any dependencies.  GNUmakefile has
+#   hooks to force a reconfigure at distribution time to get the value
+#   correct, without penalizing normal development with extra reconfigures.
+#
+# .version - present in a checked-out repository and in a distribution
+#   tarball.  Usable in dependencies, particularly for files that don't
+#   want to depend on config.h but do want to track version changes.
+#   Delete this file prior to any autoconf run where you want to rebuild
+#   files to pick up a version string change; and leave it stale to
+#   minimize rebuild time after unrelated changes to configure sources.
+#
+# As with any generated file in a VC'd directory, you should add
+# /.version to .gitignore, so that you don't accidentally commit it.
+# .tarball-version is never generated in a VC'd directory, so needn't
+# be listed there.
+#
+# Use the following line in your configure.ac, so that $(VERSION) will
+# automatically be up-to-date each time configure is run (and note that
+# since configure.ac no longer includes a version string, Makefile rules
+# should not depend on configure.ac for version updates).
+#
+# AC_INIT([GNU project],
+#         m4_esyscmd([build-aux/git-version-gen .tarball-version]),
+#         [bug-project@example])
+#
+# Then use the following lines in your Makefile.am, so that .version
+# will be present for dependencies, and so that .version and
+# .tarball-version will exist in distribution tarballs.
+#
+# EXTRA_DIST = $(top_srcdir)/.version
+# BUILT_SOURCES = $(top_srcdir)/.version
+# $(top_srcdir)/.version:
+#	echo '$(VERSION)' > $@-t

+   --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+                  makes a change to SHA1's commit log text or metadata.
+   --append-dot append a dot to the first line of each commit message if
+                  there is no other punctuation or blank at the end.
+   --no-cluster never cluster commit messages under the same date/author
+                  header; the default is to cluster adjacent commit messages
+                  if their headers are the same and neither commit message
+                  contains multiple paragraphs.
+   --srcdir=DIR the root of the source tree, from which the .git/
+                  directory can be derived.
+   --since=DATE convert only the logs since DATE;
+                  the default is to convert all log entries.
+   --until=DATE convert only the logs older than DATE.
+   --ignore-matching=PAT ignore commit messages whose first lines match PAT.
+   --ignore-line=PAT ignore lines of commit messages that match PAT.
+   --format=FMT set format string for commit subject and body;
+                  see 'man git-log' for the list of format metacharacters;
+                  the default is '%s%n%b%n'
+   --strip-tab  remove one additional leading TAB from commit message lines.
+   --strip-cherry-pick  remove data inserted by "git cherry-pick";
+                  this includes the "cherry picked from commit ..." line,
+                  and the possible final "Conflicts:" paragraph.

+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line.  They are not copied to the output.
+
+  Copyright-paperwork-exempt: Yes
+    Append the "(tiny change)" notation to the usual "date name email"
+    ChangeLog header to mark a change that does not require a copyright
+    assignment.
+  Co-authored-by: Joe User <user\@example.com>
+    List the specified name and email address on a second
+    ChangeLog header, denoting a co-author.
+  Signed-off-by: Joe User <user\@example.com>
+    These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code.  Pairs must be separated by one or
+more blank line.

+usage="Usage: $0 [OPTION]... [CMD] FILE... [[CMD] FILE...]
+
+Sign all FILES, and process them at the destinations specified with --to.
+If CMD is not given, it defaults to uploading.  See examples below.
+
+Commands:
+  --delete                 delete FILES from destination
+  --symlink                create symbolic links
+  --rmsymlink              remove symbolic links
+  --                       treat the remaining arguments as files to upload
+
+Options:
+  --to DEST                specify a destination DEST for FILES
+                           (multiple --to options are allowed)
+  --user NAME              sign with key NAME
+  --replace                allow replacements of existing files
+  --symlink-regex[=EXPR]   use sed script EXPR to compute symbolic link names
+  -n, --dry-run            do nothing, show what would have been done
+                           (including the constructed directive file)
+  --version                output version information and exit
+  -h, --help               print this help text and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with '-latest', e.g.:
+  foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+  alpha.gnu.org:DIRECTORY
+  savannah.gnu.org:DIRECTORY
+  savannah.nongnu.org:DIRECTORY
+  ftp.gnu.org:DIRECTORY
+                           build directive files and upload files by FTP
+  download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+                           build directive files and upload files by SFTP
+  [user@]host:DIRECTORY    upload files with scp
+
+Options and commands are applied in order.  If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options.  Use this to keep your defaults.  Comments
+(#) and empty lines in $conffile are allowed.
+
+<https://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
+gives some further background.
+
+Examples:
+1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
+  gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
+
+2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
+  gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+3. Same as above, and also create symbolic links to foobar-latest.tar.*:
+  gnupload --to ftp.gnu.org:foobar \\
+           --symlink-regex \\
+           foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+4. Create a symbolic link foobar-latest.tar.gz -> foobar-1.0.tar.gz
+   and likewise for the corresponding .sig file:
+  gnupload --to ftp.gnu.org:foobar \\
+           --symlink foobar-1.0.tar.gz     foobar-latest.tar.gz \\
+                     foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
+  or (equivalent):
+  gnupload --to ftp.gnu.org:foobar \\
+           --symlink foobar-1.0.tar.gz     foobar-latest.tar.gz \\
+           --symlink foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
+
+5. Upload foobar-0.9.90.tar.gz to two sites:
+  gnupload --to alpha.gnu.org:foobar \\
+           --to sources.redhat.com:~ftp/pub/foobar \\
+           foobar-0.9.90.tar.gz
+
+6. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
+   (the -- terminates the list of files to delete):
+  gnupload --to alpha.gnu.org:foobar \\
+           --to sources.redhat.com:~ftp/pub/foobar \\
+           --delete oopsbar-0.9.91.tar.gz \\
+           -- foobar-0.9.91.tar.gz
+
+gnupload executes a program ncftpput to do the transfers; if you don't
+happen to have an ncftp package installed, the ncftpput-ftp script in
+the build-aux/ directory of the gnulib package
+(https://savannah.gnu.org/projects/gnulib) may serve as a replacement.

-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-%   @multitable @columnfractions .25 .3 .45
-%   @item ...
-%
-%   Numbers following @columnfractions are the percent of the total
-%   current hsize to be used for each column. You may use as many
-%   columns as desired.
-
-
-% Or use a template:
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item ...
-%   using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item first col stuff @tab second col stuff @tab third col
-%   @item
-%   first col stuff
-%   @tab
-%   second col stuff
-%   @tab
-%   third col
-%   @item first col stuff @tab second col stuff
-%   @tab Many paragraphs of text may be used in any column.
-%
-%         They will wrap at the width determined by the template.
-%   @item@tab@tab This will be in third column.
-%   @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.

+# Written by Jim Meyering and Joel E. Denny
+
+# This script updates an FSF copyright year list to include the current year.
+# Usage: update-copyright [FILE...]
+#
+# The arguments to this script should be names of files that contain
+# copyright statements to be updated.  The copyright holder's name
+# defaults to "Free Software Foundation, Inc." but may be changed to
+# any other name by using the "UPDATE_COPYRIGHT_HOLDER" environment
+# variable.
+#
+# For example, you might wish to use the update-copyright target rule
+# in maint.mk from gnulib's maintainer-makefile module.
+#
+# Iff a copyright statement is recognized in a file and the final
+# year is not the current year, then the statement is updated for the
+# new year and it is reformatted to:
+#
+#   1. Fit within 72 columns.
+#   2. Convert 2-digit years to 4-digit years by prepending "19".
+#   3. Expand copyright year intervals.  (See "Environment variables"
+#      below.)
+#
+# A warning is printed for every file for which no copyright
+# statement is recognized.
+#
+# Each file's copyright statement must be formatted correctly in
+# order to be recognized.  For example, each of these is fine:
+#
+#   Copyright @copyright{} 1990-2005, 2007-2009 Free Software
+#   Foundation, Inc.
+#
+#   # Copyright (C) 1990-2005, 2007-2009 Free Software
+#   # Foundation, Inc.
+#
+#   /*
+#    * Copyright &copy; 90,2005,2007-2009
+#    * Free Software Foundation, Inc.
+#    */
+#
+# However, the following format is not recognized because the line
+# prefix changes after the first line:
+#
+#   ## Copyright (C) 1990-2005, 2007-2009 Free Software
+#   #  Foundation, Inc.
+#
+# However, any correctly formatted copyright statement following
+# a non-matching copyright statements would be recognized.
+#
+# The exact conditions that a file's copyright statement must meet
+# to be recognized are:
+#
+#   1. It is the first copyright statement that meets all of the
+#      following conditions.  Subsequent copyright statements are
+#      ignored.
+#   2. Its format is "Copyright (C)", then a list of copyright years,
+#      and then the name of the copyright holder.
+#   3. The "(C)" takes one of the following forms or is omitted
+#      entirely:
+#
+#        A. (C)
+#        B. (c)
+#        C. @copyright{}
+#        D. &copy;
+#        E. ©
+#
+#   4. The "Copyright" appears at the beginning of a line, except that it
+#      may be prefixed by any sequence (e.g., a comment) of no more than
+#      5 characters -- including white space.
+#   5. Iff such a prefix is present, the same prefix appears at the
+#      beginning of each remaining line within the FSF copyright
+#      statement.  There is one exception in order to support C-style
+#      comments: if the first line's prefix contains nothing but
+#      whitespace surrounding a "/*", then the prefix for all subsequent
+#      lines is the same as the first line's prefix except with each of
+#      "/" and possibly "*" replaced by a " ".  The replacement of "*"
+#      by " " is consistent throughout all subsequent lines.
+#   6. Blank lines, even if preceded by the prefix, do not appear
+#      within the FSF copyright statement.
+#   7. Each copyright year is 2 or 4 digits, and years are separated by
+#      commas, "-", or "--".  Whitespace may appear after commas.
+#
+# Environment variables:
+#
+#   1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement
+#      is reformatted even if it does not need updating for the new
+#      year.  If unset or set to 0, only updated FSF copyright
+#      statements are reformatted.
+#   2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive
+#      copyright years (such as 90, 1991, 1992-2007, 2008) in a
+#      reformatted FSF copyright statement is collapsed to a single
+#      interval (such as 1990-2008).  If unset or set to 0, all existing
+#      copyright year intervals in a reformatted FSF copyright statement
+#      are expanded instead.
+#      If UPDATE_COPYRIGHT_USE_INTERVALS=2, convert a sequence with gaps
+#      to the minimal containing range.  For example, convert
+#      2000, 2004-2007, 2009 to 2000-2009.
+#   3. For testing purposes, you can set the assumed current year in
+#      UPDATE_COPYRIGHT_YEAR.
+#   4. The default maximum line length for a copyright line is 72.
+#      Set UPDATE_COPYRIGHT_MAX_LINE_LENGTH to use a different length.
+#   5. Set UPDATE_COPYRIGHT_HOLDER if the copyright holder is other
+#      than "Free Software Foundation, Inc.".

+   Suppress extern inline with HP-UX cc, as it appears to be broken; see
+   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+   Suppress extern inline with Sun C in standards-conformance mode, as it
+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Oracle Developer Studio 12.6
+   (Sun C 5.15 SunOS_sparc 2017/05/30).
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like <ctype.h>.  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).
+   This bug is known to occur on:
+
+     OS X 10.8 and earlier; see:
+     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+     DragonFly; see
+     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
+
+     FreeBSD; see:
+     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+   Assume DragonFly and FreeBSD will be similar.
+
+   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+   inline semantics, unless -fgnu89-inline is used.  It defines a macro
+   __GNUC_STDC_INLINE__ to indicate this situation or a macro
+   __GNUC_GNU_INLINE__ to indicate the opposite situation.
+   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+   semantics but warns, unless -fgnu89-inline is used:
+     warning: C99 inline functions are not supported; using GNU89
+     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
+   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

-   Suppress extern inline with Sun C in standards-conformance mode, as it
-   mishandles inline functions that call each other.  E.g., for 'inline void f
-   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
-   'reference to static identifier "f" in extern inline function'.
-   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
 
-   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
-   on configurations that mistakenly use 'static inline' to implement
-   functions or macros in standard C headers like <ctype.h>.  For example,
-   if isdigit is mistakenly implemented via a static inline function,
-   a program containing an extern inline function that calls isdigit
-   may not work since the C standard prohibits extern inline functions
-   from calling static functions (ISO C 99 section 6.7.4.(3).
-   This bug is known to occur on:

-<h2 class="chapter">1 Introduction</h2>
-
-<p>This document describes the Libtasn1 library that provides
-Abstract Syntax Notation One (ASN.1, as specified by the X.680 ITU-T
-recommendation) parsing and structures management,
-and Distinguished Encoding Rules (DER, as per X.690) encoding and
-decoding functions.
-</p>
-<p>The main features of this library are:
-</p>
-<ul>
-<li> On-line ASN.1 structure management that doesn&rsquo;t require any
-C code file generation.
-
-</li><li> Off-line ASN.1 structure management with C code file generation
-containing an array.
-
-</li><li> Distinguished Encoding Rules (DER) encoding support.
-
-</li><li> No limits for INTEGER and ENUMERATED values.
-
-</li><li> It&rsquo;s Free Software.
-Anybody can use, modify, and redistribute the library under the terms
-of the GNU Lesser General Public License version 2.1 or later.  The
-command line tools, self-tests and build infrastructure are licensed
-under the GNU General Public License version 3.0 or later.
-
-</li><li> Thread-safety.
-<a name="index-threads"></a>
-No global variables are used and multiple library handles and session
-handles may be used in parallel.
-
-</li><li> Portability.
-<a name="index-Porting"></a>
-The code should work on all Unix like operating systems, and Windows.
-The library itself should be portable to any C89 system, not even
-POSIX is required.
-</li></ul>

-
-<a name="index-ASN_002e1-schema"></a>
-
-<p>The parser is case sensitive.  The comments begin with <code>--</code> and
-end either with another <code>--</code>, or at the end of the respective
-line, whichever comes first.  The C-style <code>/*</code>, <code>*/</code>
-comments are not supported.
-</p>
-<p>For an example of the syntax, check the <samp>pkix.asn</samp> file
-distributed with the library.
-</p>
-<p>ASN.1 definitions must follow the syntax below:
-</p>
-<pre class="verbatim">      definitions_name {&lt;object definition&gt;}
-
-      DEFINITIONS &lt;EXPLICIT or IMPLICIT&gt; TAGS ::=
-
-      BEGIN
-
-      &lt;type and constants definitions&gt;
-
-      END
-</pre>
-<p>The <code>::=</code> token must be separate from other elements, so the
-following declaration is invalid:
-</p>
-<div class="example">
-<pre class="example">   -- INCORRECT
-   Version ::=INTEGER
-</pre></div>
-
-<p>The correct form is:
-</p>
-<div class="example">
-<pre class="example">   Version ::= INTEGER
-</pre></div>
-
-<p>Here is the list of types that the parser can manage:
-</p>
-<a name="index-Supported-ASN_002e1-types_002c-list-of"></a>
-
-<ul>
-<li> <code>INTEGER</code>;
-</li><li> <code>ENUMERATED</code>;
-</li><li> <code>BOOLEAN</code>;
-</li><li> <code>OBJECT IDENTIFIER</code>;
-</li><li> <code>NULL</code>;
-</li><li> <code>BIT STRING</code>;
-</li><li> <code>OCTET STRING</code>;
-</li><li> <code>UTCTime</code>;
-</li><li> <code>GeneralizedTime</code>;
-</li><li> <code>GeneralString</code>;
-</li><li> <code>NumericString</code>;
-</li><li> <code>IA5String</code>;
-</li><li> <code>TeletexString</code>;
-</li><li> <code>PrintableString</code>;

-</li><li> <code>SEQUENCE</code>;
-</li><li> <code>SEQUENCE OF</code>;
-</li><li> <code>SET</code>;

-</li><li> <code>CHOICE</code>;
-</li><li> <code>ANY</code>;
-</li><li> <code>ANY DEFINED BY</code>.
-
-</li></ul>
-
-<p>This version doesn&rsquo;t handle the <code>REAL</code> type.  It doesn&rsquo;t support
-the <code>AUTOMATIC TAGS</code> option, and the <code>EXPORT</code> and
-<code>IMPORT</code> sections, either.
-</p>
-<p>The <code>SIZE</code> constraints are allowed, but no check is done on them.

-</p>
-<div class="example">
-<pre class="example"> asn1_node definitions = NULL;
-</pre></div>
-
-<p>Some functions require an <code>errorDescription</code> argument of type
-<code>char *</code>, pointing to a pre-allocated buffer of at least
-<code>ASN1_MAX_ERROR_DESCRIPTION_SIZE</code> bytes size (e.g., as in
-&lsquo;<samp>char description[ASN1_MAX_ERROR_DESCRIPTION_SIZE];</samp>&rsquo;).
-</p>
-<p><code>ASN1_MAX_NAME_SIZE</code> is the maximum number of characters allowed

-<li> PREAMBLE
-
-<p>The purpose of this License is to make a manual, textbook, or other
-functional and useful document <em>free</em> in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-</p>
-<p>This License is a kind of &ldquo;copyleft&rdquo;, which means that derivative
-works of the document must themselves be free in the same sense.  It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-</p>
-<p>We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does.  But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book.  We recommend this License
-principally for works whose purpose is instruction or reference.
-</p>
-</li><li> APPLICABILITY AND DEFINITIONS
-
-<p>This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License.  Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein.  The &ldquo;Document&rdquo;, below,
-refers to any such manual or work.  Any member of the public is a
-licensee, and is addressed as &ldquo;you&rdquo;.  You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-</p>
-<p>A &ldquo;Modified Version&rdquo; of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-</p>
-<p>A &ldquo;Secondary Section&rdquo; is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document&rsquo;s overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject.  (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.)  The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-</p>
-<p>The &ldquo;Invariant Sections&rdquo; are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License.  If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant.  The Document may contain zero
-Invariant Sections.  If the Document does not identify any Invariant
-Sections then there are none.
-</p>
-<p>The &ldquo;Cover Texts&rdquo; are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License.  A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-</p>
-<p>A &ldquo;Transparent&rdquo; copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters.  A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text.  A copy that is not &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
-</p>
-<p>Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, LaTeX input
-format, SGML or XML using a publicly available
-DTD, and standard-conforming simple HTML,
-PostScript or PDF designed for human modification.  Examples
-of transparent image formats include PNG, XCF and
-JPG.  Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, SGML or
-XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML,
-PostScript or PDF produced by some word processors for
-output purposes only.
-</p>
-<p>The &ldquo;Title Page&rdquo; means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page.  For works in
-formats which do not have any title page as such, &ldquo;Title Page&rdquo; means
-the text near the most prominent appearance of the work&rsquo;s title,
-preceding the beginning of the body of the text.
-</p>
-<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
-of the Document to the public.
-</p>
-<p>A section &ldquo;Entitled XYZ&rdquo; means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language.  (Here XYZ stands for a
-specific section name mentioned below, such as &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.)  To &ldquo;Preserve the Title&rdquo;
-of such a section when you modify the Document means that it remains a
-section &ldquo;Entitled XYZ&rdquo; according to this definition.
-</p>
-<p>The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document.  These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-</p>
-</li><li> VERBATIM COPYING
-
-<p>You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License.  You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute.  However, you may accept
-compensation in exchange for copies.  If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-</p>
-<p>You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-</p>
-</li><li> COPYING IN QUANTITY
-
-<p>If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document&rsquo;s license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover.  Both covers must also clearly and legibly identify
-you as the publisher of these copies.  The front cover must present
-the full title with all words of the title equally prominent and
-visible.  You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-</p>
-<p>If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-</p>
-<p>If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-</p>
-<p>It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-</p>
-</li><li> MODIFICATIONS
-
-<p>You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it.  In addition, you must do these things in the Modified Version:
-</p>
-<ol type="A" start="1">
-<li> Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document).  You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-</li><li> List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-</li><li> State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-</li><li> Preserve all the copyright notices of the Document.
-
-</li><li> Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-</li><li> Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-</li><li> Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document&rsquo;s license notice.
-
-</li><li> Include an unaltered copy of this License.
-
-</li><li> Preserve the section Entitled &ldquo;History&rdquo;, Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page.  If
-there is no section Entitled &ldquo;History&rdquo; in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-</li><li> Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on.  These may be placed in the &ldquo;History&rdquo; section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-</li><li> For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-</li><li> Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles.  Section numbers
-or the equivalent are not considered part of the section titles.
-
-</li><li> Delete any section Entitled &ldquo;Endorsements&rdquo;.  Such a section
-may not be included in the Modified Version.
-
-</li><li> Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
-to conflict in title with any Invariant Section.
-
-</li><li> Preserve any Warranty Disclaimers.
-</li></ol>
-
-<p>If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant.  To do this, add their titles to the
-list of Invariant Sections in the Modified Version&rsquo;s license notice.
-These titles must be distinct from any other section titles.
-</p>
-<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
-nothing but endorsements of your Modified Version by various
-parties&mdash;for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-</p>
-<p>You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version.  Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity.  If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-</p>
-<p>The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-</p>
-</li><li> COMBINING DOCUMENTS
-
-<p>You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-</p>
-<p>The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy.  If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-</p>
-<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
-in the various original documents, forming one section Entitled
-&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
-and any sections Entitled &ldquo;Dedications&rdquo;.  You must delete all
-sections Entitled &ldquo;Endorsements.&rdquo;
-</p>
-</li><li> COLLECTIONS OF DOCUMENTS
-
-<p>You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-</p>
-<p>You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-</p>
-</li><li> AGGREGATION WITH INDEPENDENT WORKS
-
-<p>A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an &ldquo;aggregate&rdquo; if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation&rsquo;s users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-</p>
-<p>If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document&rsquo;s Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-</p>
-</li><li> TRANSLATION
-
-<p>Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections.  You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers.  In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-</p>
-<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-</p>
-</li><li> TERMINATION
-
-<p>You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-</p>
-<p>However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-</p>
-<p>Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-</p>
-<p>Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-</p>
-</li><li> FUTURE REVISIONS OF THIS LICENSE
-
-<p>The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time.  Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.  See
-<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
-</p>
-<p>Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License &ldquo;or any later version&rdquo; applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation.  If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.  If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy&rsquo;s public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-</p>
-</li><li> RELICENSING
-
-<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works.  A
-public wiki that anybody can edit is an example of such a server.  A
-&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-</p>
-<p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-</p>
-<p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
-in part, as part of another Document.
-</p>
-<p>An MMC is &ldquo;eligible for relicensing&rdquo; if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-</p>
-<p>The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.
-</p>

-<a name="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></a>
-<h3 class="heading">ADDENDUM: How to use this License for your documents</h3>
-
-<p>To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-</p>
-<div class="smallexample">
-<pre class="smallexample">  Copyright (C)  <var>year</var>  <var>your name</var>.
-  Permission is granted to copy, distribute and/or modify this document
-  under the terms of the GNU Free Documentation License, Version 1.3
-  or any later version published by the Free Software Foundation;
-  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
-  Texts.  A copy of the license is included in the section entitled ``GNU
-  Free Documentation License''.
-</pre></div>
-
-<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the &ldquo;with&hellip;Texts.&rdquo; line with this:
-</p>
-<div class="smallexample">
-<pre class="smallexample">    with the Invariant Sections being <var>list their titles</var>, with
-    the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
-    being <var>list</var>.
-</pre></div>
-
-<p>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-</p>
-<p>If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

+# Fuzzers
+
+These are fuzzers designed for use with `libFuzzer` or `afl`. They can
+be used to run on Google's OSS-Fuzz (https://github.com/google/oss-fuzz/).
+
+The convention used here is that the initial values for each parser fuzzer
+are taken from the $NAME.in/ and $NAME.repro/ directories.
+
+Crash reproducers from OSS-Fuzz are put into $NAME.repro directory for
+regression testing with top dir 'make check'.
+
+
+# Running a fuzzer locally using clang
+
+Use the following commands on top dir (best with clang-9 or higher):
+```
+export CC=clang-9
+export CFLAGS="-O1 -g -fno-omit-frame-pointer -gline-tables-only -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION -fsanitize=undefined,integer,nullability -fsanitize=address -fsanitize-address-use-after-scope -fsanitize=fuzzer-no-link"
+export CFLAGS="$CFLAGS -fsanitize=bool,array-bounds,float-divide-by-zero,function,integer-divide-by-zero,return,shift,signed-integer-overflow,unsigned-integer-overflow,vla-bound,vptr -fno-sanitize-recover=bool,array-bounds,float-divide-by-zero,function,integer-divide-by-zero,return,shift,signed-integer-overflow,vla-bound,vptr"
+./configure --enable-fuzzing --disable-doc --disable-gcc-warnings
+make clean
+make -j$(nproc)
+cd fuzz
+
+# run libtasn1_array2tree_fuzzer
+UBSAN_OPTIONS=print_stacktrace=1 ASAN_SYMBOLIZER_PATH=/usr/lib/llvm-9/bin/llvm-symbolizer \
+  ./run-clang.sh libtasn1_array2tree_fuzzer
+```
+
+If you see a crash, then a crash corpora is written that can be used for further
+investigation. E.g.
+```
+==2410==ERROR: AddressSanitizer: heap-use-after-free on address 0x602000004e90 at pc 0x00000049cf9c bp 0x7fffb5543f70 sp 0x7fffb5543720
+...
+Test unit written to ./crash-adc83b19e793491b1c6ea0fd8b46cd9f32e592fc
+```
+
+To reproduce the crash:
+```
+./libtasn1_array2tree_fuzzer < ./crash-adc83b19e793491b1c6ea0fd8b46cd9f32e592fc
+```
+
+You can also copy/move that file into libtasn1_array2tree_fuzzer.repro/
+and re-build the project without fuzzing for a valgrind run, if you prefer that.
+Just a `./configure --enable-valgrind-tests` and a `make check` should reproduce it.
+
+
+# Running a fuzzer using AFL
+
+Use the following commands on top dir:
+
+```
+$ CC=afl-clang-fast ./configure --disable-doc
+$ make -j$(nproc) clean all
+$ cd fuzz
+$ ./run-afl.sh libtasn1_array2tree_fuzzer
+```
+
+# Fuzz code coverage using the corpus directories *.in/
+
+Code coverage reports currently work best with gcc+lcov+genhtml.
+
+In the top directory:
+```
+CC=gcc CFLAGS="-O0 -g" ./configure --disable-doc --disable-manywarnings
+make fuzz-coverage
+xdg-open lcov/index.html
+```
+
+Each fuzzer target has it's own files/functions to cover, e.g.
+`libtasn1_array2tree_fuzzer` covers array2tree.
+
+To work on corpora for better coverage, `cd fuzz` and use e.g.
+`./view-coverage.sh libtasn1_array2tree_fuzzer`.

+/* Usage suggestions:
+
+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+       - C99 allows the use of (_Bool)0.0 in constant expressions, but
+         this substitute cannot always provide this property.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';
+   this isn't required, but 'bool' is more common.  */

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If 'getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If 'getopt' finds another option character, it returns that character,
+   updating 'optind' and 'nextchar' so that the next call to 'getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, 'getopt' returns -1.
+   Then 'optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set 'opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in 'optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in 'optarg', otherwise 'optarg' is set to zero.
+
+   If OPTSTRING starts with '-' or '+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with '--' instead of '-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a '=', or else the in next ARGV-element.
+   When 'getopt' finds a long-named option, it returns 0 if that option's
+   'flag' field is nonzero, the value of the option's 'val' field
+   if the 'flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of 'struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */

+
+/* The type 'idx_t' holds an (array) index or an (object) size.
+   Its implementation promotes to a signed integer type,
+   which can hold the values
+     0..2^63-1 (on 64-bit platforms) or
+     0..2^31-1 (on 32-bit platforms).
+
+   Why a signed integer type?
+
+     * Security: Signed types can be checked for overflow via
+       '-fsanitize=undefined', but unsigned types cannot.
+
+     * Comparisons without surprises: ISO C99 § 6.3.1.8 specifies a few
+       surprising results for comparisons, such as
+
+           (int) -3 < (unsigned long) 7  =>  false
+           (int) -3 < (unsigned int) 7   =>  false
+       and on 32-bit machines:
+           (long) -3 < (unsigned int) 7  =>  false
+
+       This is surprising because the natural comparison order is by
+       value in the realm of infinite-precision signed integers (ℤ).
+
+       The best way to get rid of such surprises is to use signed types
+       for numerical integer values, and use unsigned types only for
+       bit masks and enums.
+
+   Why not use 'size_t' directly?
+
+     * Because 'size_t' is an unsigned type, and a signed type is better.
+       See above.
+
+   Why not use 'ssize_t'?
+
+     * 'ptrdiff_t' is more portable; it is standardized by ISO C
+       whereas 'ssize_t' is standardized only by POSIX.
+
+     * 'ssize_t' is not required to be as wide as 'size_t', and some
+       now-obsolete POSIX platforms had 'size_t' wider than 'ssize_t'.
+
+     * Conversely, some now-obsolete platforms had 'ptrdiff_t' wider
+       than 'size_t', which can be a win and conforms to POSIX.
+
+   Won't this cause a problem with objects larger than PTRDIFF_MAX?
+
+     * Typical modern or large platforms do not allocate such objects,
+       so this is not much of a problem in practice; for example, you
+       can safely write 'idx_t len = strlen (s);'.  To port to older
+       small platforms where allocations larger than PTRDIFF_MAX could
+       in theory be a problem, you can use Gnulib's ialloc module, or
+       functions like ximalloc in Gnulib's xalloc module.
+
+   Why not use 'ptrdiff_t' directly?
+
+     * Maintainability: When reading and modifying code, it helps to know that
+       a certain variable cannot have negative values.  For example, when you
+       have a loop
+
+         int n = ...;
+         for (int i = 0; i < n; i++) ...
+
+       or
+
+         ptrdiff_t n = ...;

+   The INT_<op>_RANGE_OVERFLOW macros return 1 if the corresponding C

+   These macros do not rely on undefined or implementation-defined behavior.
+   Although their implementations are simple and straightforward,

+
+   These macros may evaluate their arguments zero or multiple times,
+   so the arguments should not have side effects.  The arithmetic
+   arguments (including the MIN and MAX arguments) must be of the same
+   integer type after the usual arithmetic conversions, and the type
+   must have minimum value MIN and maximum MAX.  Unsigned types should
+   use a zero MIN of the proper type.
+
+   Because all arguments are subject to integer promotions, these

+
+   The INT_<op>_OVERFLOW macros return 1 if the corresponding C operators

+   The INT_<op>_WRAPV macros compute the low-order bits of the sum,
+   difference, and product of two C integers, and return 1 if these
+   low-order bits are not numerically correct.
+   These macros work correctly on all known practical hosts, and do not rely
+   on undefined behavior due to signed arithmetic overflow.
+
+   Example usage, assuming A and B are long int:
+
+     if (INT_MULTIPLY_OVERFLOW (a, b))
+       printf ("result would overflow\n");
+     else
+       printf ("result is %ld (no overflow)\n", a * b);

+   Example usage with WRAPV flavor:
+
+     long int result;

+   by zero, for bad shift counts, or for shifting negative numbers.
+
+   These macros may evaluate their arguments zero or multiple times, so the
+   arguments should not have side effects.
+
+   The WRAPV macros are not constant expressions.  They support only
+   +, binary -, and *.
+
+   Because the WRAPV macros convert the result, they report overflow
+   in different circumstances than the OVERFLOW macros do.  For
+   example, in the typical case with 16-bit 'short' and 32-bit 'int',
+   if A, B and *R are all of type 'short' then INT_ADD_OVERFLOW (A, B)
+   returns false because the addition cannot overflow after A and B
+   are converted to 'int', whereas INT_ADD_WRAPV (A, B, R) returns
+   true or false depending on whether the sum fits into 'short'.
+
+   These macros are tuned for their last input argument being a constant.
+
+   A, B, and *R should be integers; they need not be the same type,
+   and they need not be all signed or all unsigned.
+   However, none of the integer types should be bit-precise,
+   and *R's type should not be char, bool, or an enumeration type.
+

+   Example usage:
+
+     long int result;
+     if (INT_ADD_OK (a, b, &result))
+       printf ("result is %ld\n", result);
+     else
+       printf ("overflow\n");
+
+   A, B, and *R should be integers; they need not be the same type,
+   and they need not be all signed or all unsigned.
+   However, none of the integer types should be bit-precise,
+   and *R's type should not be char, bool, or an enumeration type.
+
+   These macros work correctly on all known practical hosts, and do not rely
+   on undefined behavior due to signed arithmetic overflow.
+
+   These macros are not constant expressions.
+
+   These macros may evaluate their arguments zero or multiple times, so the
+   arguments should not have side effects.
+
+   These macros are tuned for B being a constant.  */

+/* Usage suggestions:
+
+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+       - C99 allows the use of (_Bool)0.0 in constant expressions, but
+         this substitute cannot always provide this property.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';
+   this isn't required, but 'bool' is more common.  */

+/* Set up the following warnings, based on which modules are in use.
+   GNU Coding Standards discourage the use of fseek, since it imposes
+   an arbitrary limitation on some 32-bit hosts.  Remember that the
+   fseek module depends on the fseeko module, so we only have three
+   cases to consider:
+
+   1. The developer is not using either module.  Issue a warning under
+   GNULIB_POSIXCHECK for both functions, to remind them that both
+   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
+   impact on this warning.
+
+   2. The developer is using both modules.  They may be unaware of the
+   arbitrary limitations of fseek, so issue a warning under
+   GNULIB_POSIXCHECK.  On the other hand, they may be using both
+   modules intentionally, so the developer can define
+   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+   is safe, to silence the warning.
+
+   3. The developer is using the fseeko module, but not fseek.  Gnulib
+   guarantees that fseek will still work around platform bugs in that
+   case, but we presume that the developer is aware of the pitfalls of
+   fseek and was trying to avoid it, so issue a warning even when
+   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
+   defined to silence the warning in particular compilation units.
+   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+   fseek gets defined as a macro, it is recommended that the developer
+   uses the fseek module, even if he is not calling the fseek function.
+
+   Most gnulib clients that perform stream operations should fall into
+   category 3.  */

+/* Each of these macros verifies that its argument R is nonzero.  To
+   be portable, R should be an integer constant expression.  Unlike
+   assert (R), there is no run-time overhead.
+
+   If _Static_assert works, verify (R) uses it directly.  Similarly,
+   _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
+   that is an operand of sizeof.
+
+   The code below uses several ideas for C++ compilers, and for C
+   compilers that do not support _Static_assert:
+
+   * The first step is ((R) ? 1 : -1).  Given an expression R, of
+     integral or boolean or floating-point type, this yields an
+     expression of integral type, whose value is later verified to be
+     constant and nonnegative.
+
+   * Next this expression W is wrapped in a type
+     struct _gl_verify_type {
+       unsigned int _gl_verify_error_if_negative: W;
+     }.
+     If W is negative, this yields a compile-time error.  No compiler can
+     deal with a bit-field of negative size.
+
+     One might think that an array size check would have the same
+     effect, that is, that the type struct { unsigned int dummy[W]; }
+     would work as well.  However, inside a function, some compilers
+     (such as C++ compilers and GNU C) allow local parameters and
+     variables inside array size expressions.  With these compilers,
+     an array size check would not properly diagnose this misuse of
+     the verify macro:
+
+       void function (int n) { verify (n < 0); }
+
+   * For the verify macro, the struct _gl_verify_type will need to
+     somehow be embedded into a declaration.  To be portable, this
+     declaration must declare an object, a constant, a function, or a
+     typedef name.  If the declared entity uses the type directly,
+     such as in
+
+       struct dummy {...};
+       typedef struct {...} dummy;
+       extern struct {...} *dummy;
+       extern void dummy (struct {...} *);
+       extern struct {...} *dummy (void);
+
+     two uses of the verify macro would yield colliding declarations
+     if the entity names are not disambiguated.  A workaround is to
+     attach the current line number to the entity name:
+
+       #define _GL_CONCAT0(x, y) x##y
+       #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
+       extern struct {...} * _GL_CONCAT (dummy, __LINE__);
+
+     But this has the problem that two invocations of verify from
+     within the same macro would collide, since the __LINE__ value
+     would be the same for both invocations.  (The GCC __COUNTER__
+     macro solves this problem, but is not portable.)
+
+     A solution is to use the sizeof operator.  It yields a number,
+     getting rid of the identity of the type.  Declarations like
+
+       extern int dummy [sizeof (struct {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+     can be repeated.
+
+   * Should the implementation use a named struct or an unnamed struct?
+     Which of the following alternatives can be used?
+
+       extern int dummy [sizeof (struct {...})];
+       extern int dummy [sizeof (struct _gl_verify_type {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+       extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
+
+     In the second and sixth case, the struct type is exported to the
+     outer scope; two such declarations therefore collide.  GCC warns
+     about the first, third, and fourth cases.  So the only remaining
+     possibility is the fifth case:
+
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+   * GCC warns about duplicate declarations of the dummy function if
+     -Wredundant-decls is used.  GCC 4.3 and later have a builtin
+     __COUNTER__ macro that can let us generate unique identifiers for
+     each dummy function, to suppress this warning.
+
+   * This implementation exploits the fact that older versions of GCC,
+     which do not support _Static_assert, also do not warn about the
+     last declaration mentioned above.
+
+   * GCC warns if -Wnested-externs is enabled and 'verify' is used
+     within a function body; but inside a function, you can always
+     arrange to use verify_expr instead.
+
+   * In C++, any struct definition inside sizeof is invalid.
+     Use a template type to work around the problem.  */

+

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
+   this feature, it expands to empty.
+
+   These macros are useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.
+   _GL_WARN_ON_USE is for functions with 'extern' linkage.
+   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+   linkage.
+
+   However, one of the reasons that a function is a portability trap is
+   if it has the wrong signature.  Declaring FUNCTION with a different
+   signature in C is a compilation error, so this macro must use the
+   same type as any existing declaration so that programs that avoid
+   the problematic FUNCTION do not fail to compile merely because they
+   included a header that poisoned the function.  But this implies that
+   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+   have a declaration.  Use of this macro implies that there must not
+   be any other macro hiding the declaration of FUNCTION; but
+   undefining FUNCTION first is part of the poisoning process anyway
+   (although for symbols that are provided only via a macro, the result
+   is a compilation error rather than a warning containing
+   "literal string").  Also note that in C++, it is only safe to use if
+   FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+     [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     rpl_environ (void) { return &environ; }
+     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+     # undef environ
+     # define environ (*rpl_environ ())
+     #endif
+   or better (avoiding contradictory use of 'static' and 'extern'):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+     rpl_environ (void) { return &environ; }
