-# in config.h
-# (e.g. '#define ABSOLUTE_SYS_INTTYPES_H "///usr/include/sys/inttypes.h"').
-# The three "///" are to pacify Sun C 5.8, which otherwise would say

-# Use '""', not '<>', so that the /// cannot be confused with a C99 comment.

-dnl From Paul Eggert and Derek Price.
-
-dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
-dnl
-dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
-dnl 'include' otherwise.
-dnl
-dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
-dnl supports it in the special case that it is the first include directive in
-dnl the given file, or to 'include' otherwise.
-dnl
-dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
-dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
-dnl '#pragma GCC system_header' has the same effect as if the file was found
-dnl through the include search path specified with '-isystem' options (as
-dnl opposed to the search path specified with '-I' options). Namely, gcc
-dnl does not warn about some things, and on some systems (Solaris and Interix)
-dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
-dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
-dnl of plain '__STDC__'.
-dnl
-dnl PRAGMA_COLUMNS can be used in files that override system header files, so
-dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
-dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
-dnl has the effect of truncating the lines of that file and all files that it
-dnl includes to 80 columns) and the gnulib file has lines longer than 80
-dnl columns.

-# gl_WARN_ON_USE_PREPARE(INCLUDES, NAMES)
-# ---------------------------------------
-# For each whitespace-separated element in the list of NAMES, define
-# HAVE_RAW_DECL_name if the function has a declaration among INCLUDES
-# even after being undefined as a macro.
-#
-# See warn-on-use.h for some hints on how to poison function names, as
-# well as ideas on poisoning global variables and macros.  NAMES may
-# include global variables, but remember that only functions work with
-# _GL_WARN_ON_USE.  Typically, INCLUDES only needs to list a single
-# header, but if the replacement header pulls in other headers because
-# some systems declare functions in the wrong header, then INCLUDES
-# should do likewise.
-#
-# It is generally safe to assume declarations for functions declared
-# in the intersection of C89 and C11 (such as printf) without
-# needing gl_WARN_ON_USE_PREPARE.
