	Link gpgme-tool directly to libassuan, as it uses its interface.
	* src/Makefile.am (gpgme_tool_LDADD): Add @LIBASSUAN_LIBS@.

2012-01-19  Werner Koch  <wk@gnupg.org>

	Support the mingw-w64 toolchain.
	* autogen.sh (build-w32): Add i686-w64-mingw32 to the toolprefix.

	Fix Solaris problems with ttyname_r.
	* m4/gnupg-ttyname.m4: New.  Based on ttyname_r from gnulib.
	* src/ttyname_r.c (_gpgme_ttyname_r): Rename from ttyname_r.
	Implement hacks required for Solaris and possible other non-fully
	Posix systems.
	* src/util.h: Include unistd.h.  Redefine ttyname_r depending on
	REPLACE_TTYNAME_R and put it into the gpgme name space.

	Try to make configure.ac a bit smaller.
	* configure.ac: Move header checks.

	For W32 use a build number instead of abbreviated commit id.
	We would need to use a shortened commit id so that it fits into an 16
	bit Windows variable.  Further it is a random number and not something
	increasing.  Thus a build number made up from the day of the year and
	the hour is much more useful to describe a build number for a specific
	revision.
	* configure.ac [W32]: Replace BUILD_REVISION by BUILD_NUMBER.
	* src/versioninfo.rc.in: Ditto.

	Adjust configure.ac for modern autoconf.
	* configure.ac: Minor cleanups.

	Update to libtool 2.4.2.
	* ltmain.sh, m4/libtool.m4, m4/ltoptions.m4, m4/ltversion.m4,
	* m4/lt~obsolete.m4: Update.

	Add ttyname_r check macro from gnulib.
	* m4/gnupg-ttyname.m4: New. Taken from current gnulib.

2011-12-02  Werner Koch  <wk@gnupg.org>

	Generate the ChangeLog from commit logs.
	* build-aux/gitlog-to-changelog: New script.  Taken from gnulib.
	* build-aux/git-log-fix: New file.
	* build-aux/git-log-footer: New file.
	* build-aux/git-hook/commit-msg: New script.
	* doc/HACKING: New file.
	* ChangeLog: New file.
	* Makefile.am (EXTRA_DIST): Add new files.
	(gen-ChangeLog): New.
	(dist-hook): Run gen-ChangeLog.
	* autogen.sh: Install commit-msg hook for git.

	Rename all ChangeLog files to ChangeLog-2011.

2011-12-02  Werner Koch  <wk@gnupg.org>

	NB: Changes done before December 1st, 2011 are described in
	per directory files named ChangeLog-2011.  See doc/HACKING for
	details.
