	Use Gnulib environ module (Bug#9772).
	* m4/environ.m4: New file, from gnulib.
	* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

	Use Gnulib stdalign module (Bug#9772, Bug#9960).
	This should improve portability of macros like alignof and DECL_ALIGN.
	* lib/stdalign.in.h, m4/stdalign.m4: New files, from gnulib.
	* .bzrignore: Add lib/stdalign.h.
	* config.bat: Do not set NO_DECL_ALIGN; no longer needed.
	Copy lib/stdalign.in.h to lib/stdalign.in-h as needed.
	* configure.ac (HAVE_ATTRIBUTE_ALIGNED): Remove the code that
	fiddles with this, as gnulib now does this for us.

2012-07-17  Paul Eggert  <eggert@cs.ucla.edu>

	Fix regression with pthread_sigmask on FreeBSD (Bug#11884).
	* configure.ac: Configure gnulib at the end, not before running
	pkg-config.  This restores the behavior before 2012-06-22, when
	higher-resolution time stamps were added, and fixes a bug whereby
	LIB_PTHREAD was not used and gnulib's part of 'configure'
	therefore incorrectly assumed that pthread_sigmask wasn't working.
	Fix the problem with -lrt and clock_gettime a different way.
	This should complete the fix for Bug#11884.
	(pre_PKG_CONFIG_CFLAGS, pre_PKG_CONFIG_LIBS): New shell vars.

	2012-07-09 timespec: mark functions with const attributes

146 147 148
	Rename configure.in to configure.ac (Bug#11603).
	The name 'configure.in' has been obsolescent for quite some time,
	and the next release of Autoconf will generate warnings for it.
149 150
	See commit 'v2.69-4-g560f16b' of 2012-05-06, "general: deprecate

	Improve static checking when configured --with-ns.
	See Samuel Bronson's remarks in
	<http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00146.html>.
	* configure.in (WARN_CFLAGS): Omit -Wunreachable-code, as it's
	a no-op with recent GCC and harmful in earlier ones.
	Omit -Wsync-nand, as it's irrelevant to Emacs and provokes a
	warning when compiling with ObjC.  Always omit
	-Wunsafe-loop-optimizations, as we don't mind when optimization is
	being done correctly.

181 182
2012-07-07  Glenn Morris  <rgm@gnu.org>

183 184
	* configure.in (BROKEN_SA_RESTART): Doc fix.

185 186 187 188 189 190
	* configure.in: Rather than checking for things then undef'ing
	them on some platforms, simply don't check for them.
	(getwd): Don't check for it on unixware.
	(random, rint): Don't check for these on hpux.
	(res_init, libresolv): Don't check for these on darwin.

200 201
	* configure.in: Document --enable-gcc-warnings better.

202 203 204 205 206
	Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
	This is safer than strcasecmp, which has unspecified behavior
	outside the POSIX locale and in practice sometimes does not work
	in multibyte locales.  Similarly for c_strncasecmp and strncasecmp.
	* configure.in (strcasecmp, strncasecmp): Remove checks.
207

208 209 210 211

	* lib/makefile.w32-in ($(GNULIBOBJS)): Depend on stamp_BLD.  This

	Switch from NO_RETURN to C11's _Noreturn (Bug#11750).

	* configure.in: Coalesce some function checking.
	This makes 'configure' a bit smaller.
	Prefer AC_CHECK_FUNCS_ONCE for functions that we always check for.

	Remove --disable-maintainer-mode option from 'configure'.  (Bug#11555)
	It is confusingly named and rarely useful.  See, for example,
	<http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00089.html>.

	Make 'configure' a bit smaller and faster.
	* configure.in (INSTALL_INFO): Set it with one call to
	AC_PATH_PROG, not three.
	(PKG_CONFIG): Hoist this out of PKG_CHECK_MODULES, since it's
	so likely that it'll be needed.
	(AC_CHECK_HEADERS_ONCE): Prefer to AC_CHECK_HEADERS where either works.

	Assume gnulib does largefile.
	Gnulib does the largefile configuration anyway, so when configure.in
	invokes AC_SYS_LARGEFILE, that bloats 'configure' unnecessarily.
	* configure.in (AC_SYS_LARGEFILE): Remove.

	Merge from gnulib.  (Bug#11527)

	The build procedure now creates <stdalign.h> and <sys/types.h> for
	older hosts that lack a working <stdalign.h> or whose
	<sys/types.h> does not define pid_t, size_t, ssize_t, mode_t.  New
	symbols such as WINDOWS_64_BIT_OFF_T may require attention in the
	msdos and nt builds.

	Here is a precis of gnulib changes that seem relevant; please see
	the gnulib ChangeLog for details.

	Use full name for m4/gnulib-comp.m4.  (Bug#11529)
	Previously the file was named m4/gl-comp.m4 due to DOS 8+3 restrictions,
	even though the file's name in gnulib is m4/gnulib-comp.m4.
	This had a problem when merging from gnulib, as the code temporarily
	renamed it to the full name, causing problems when interrupted.
	Now the file has its full name, with the idea that we will find
	a solution for MS-DOS that does not affect the rest of Emacs.
	* m4/gnulib-comp.m4: Rename from m4/gl-comp.m4.

599 600 601 602 603 604 605 606
	Make merging from gnulib a script, not a makefile action.
	Putting it in a makefile has some problems with reflection, as
	merging from gnulib updates 'configure', which can update the makefile.
	Putting it in a standalone script breaks this loop.
	* Makefile.in (gnulib_srcdir, $(gnulib_srcdir), DOS_gnulib_comp.m4)
	(GNULIB_MODULES, GNULIB_TOOL_FLAGS, sync-from-gnulib):
	Remove, moving the actions to the script admin/merge-gnulib.

	(AC_PROG_INSTALL, AC_PROG_MKDIR_P, AC_PROG_RANLIB): Comment out,

	obsolete -- Sun dropped support for it in 2006 -- and without

	* m4/signal_h.m4, m4/time_h.m4, m4/unistd_h.m4:

	doesn't affect Emacs.

	This is to fix the following problems:
	 . On FreeBSD 6.4, HP-UX 11.31, and Solaris 9, and when Emacs is
	   configured not to use gtk or any other thread-using library,
	   signals aren't blocked correctly.
	 . On IRIX 6.5 it fixes an unwanted clash between Emacs's
	   and IRIX's signal handling.
	 . On Cygwin 1.7.5 it works around an incompatibility with
	   the system pthread_sigmask.
	 . On MacOS X 10.5 (32-bit), files whose inode numbers
	   exceed 2**31 cannot be read or manipulated.
	 . pthread_sigmask: Actually use results of gl_THREADLIB.
	 . strtoimax, strtoumax: Avoid link error on OSF/1 with DTK cc.
	 . find 'ar' program that fits with --host argument.
	 . Allow the user to override the choice of AR, ARFLAGS, RANLIB.
1205 1206 1207 1208
	* autogen/README: Update destination list.
	* autogen/copy_autogen, autogen/update_autogen, .bzrignore:
	The autogenerated files compile, config.guess,
	config.sub, depcomp, install-sh, and missing are now in build-aux.

	* m4/largefile.m4: New file, so that Emacs does not mess up when
	accessing files with large inode numbers in MacOS X 10.5 and later.
	* m4/nocrash.m4: New file, to avoid triggering background debugger
	and/or create core dumps during 'configure'.
	* build-aux/move-if-change: Renamed from move-if-change.
	* build-aux/snippet/arg-nonnull.h: Renamed from arg-nonnull.h.
	* build-aux/snippet/c++defs.h: Renamed from c++defs.h.
	* build-aux/snippet/warn-on-use.h: Renamed from warn-on-use.h.
	* build-aux/snippet/_Noreturn.h: New file, for draft C1X _Noreturn.
	* Makefile.in (epaths-force, sync-from-gnulib):
	move-if-change is now in build-aux.
	(GNULIB_TOOL_FLAGS): Avoid threadlib; this is now a prerequisite
	of gnulib's pthread_sigmask module, but Emacs doesn't need it.
	(mkdir): install-sh is now in build-aux.
	* config.bat: c++defs.h is now in build-aux/snippets.
	* configure.in: Specify AC_CONFIG_AUX_DIR with build-aux (the
	usual parameter).
	* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
	* lib/makefile.w32-in (ARG_NONNULL_H): arg-nonnull.h moved
	to build-aux/snippet.
	* lib/pthread_sigmask.c, lib/stdlib.in.h, m4/extensions.m4:
	* m4/getopt.m4, m4/gnulib-common.m4, m4/pthread_sigmask.m4:
	Merge from gnuilib.  This fixes porting bugs on Cygwin, Irix, and
	Solaris, enables MacOS extensions, and enables nocrash during
	'configure'.
	* make-dist: Adjust to new build-aux and build-aux/snippit dirs.

	Remove unreachable pattern hppa*-*-linux-gnu*.
	Also, remove ia64*-hp-hpux1[1-9]*, as it also sets machine=hp800,

	Assume support for memcmp, memcpy, memmove, memset.
	This simplifies the code a bit.  All current platforms have these,
	as they are required for C89.  If this turns into a problem we
	can add the gnulib modules for these (a 1-line change to Makefile.in).
	* configure.in: Don't check for memcmp, memcpy, memmove, memset.

	test, which runs afoul of Automake installations where, for example,
	/usr/share/aclocal contains a copy of gl_THREADLIB.
	Problem reported by Sven Joachim in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00529.html>.
	This is just a quick temporary fix, specific to Emacs; I'll work
