+
+ Fix port to 32-bit AIX with xlc (Bug#17598).
+ This doesn't fix Bug#17598, but it does fix a regression since Emacs
+ built with xlc until recently, and perhaps it'll help us fix Bug#17598.
+ * configure.ac (GC_SETJMP_WORKS): Define for AIX, too.
+ Merge from gnulib, incorporating:
+ 2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
+ * lib/ftoastr.c: Update from gnulib.

+
+ Merge from gnulib, incorporating:
+ 2014-06-02 acl: apply pure attribute to two functions
+ 2014-06-01 gnulib-common.m4: add _GL_UNUSED_LABEL
+ 2014-05-31 dup2, fcntl, fcntl-h: port to AIX 7.1
+ 2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
+ * lib/acl-internal.h, lib/fcntl.in.h, lib/ftoastr.h:

+ Update from gnulib.
+
+2014-06-01 Juanma Barranquero <lekktu@gmail.com>
+
+ * configure.ac (C_HEAP_SWITCH): Raise HEAPSIZE value for 32-bit
+ builds on Windows.
+
+2014-05-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (pthread_sigmask): Look in LIB_PTHREAD too (Bug#17561).
+ Fixes configuration glitch found in <http://bugs.gnu.org/17561#59>.
+
+2014-05-29 Eli Zaretskii <eliz@gnu.org>
+
+ * configure.ac (ADDSECTION, TEMACS_POST_LINK): Don't compute,
+ unused.
+
+2014-05-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ Don't substitute sigprocmask for pthread_sigmask (Bug#17561).
+ sigprocmask isn't portable in a multithreaded process.
+ * configure.ac (gl_THREADLIB): Remove dummy.
+ Merge from gnulib, incorporating:
+ 2014-05-28 pthread_sigmask, timer-time: use gl_THREADLIB only if needed

+ * configure.ac: Explicitly drop some ancient Solaris versions.
+

+
+ * configure.ac (C_HEAP_SWITCH): Define for different values of
+ dumped heap size depending on 32/64bits arch on Windows.
+ Don't check for pthreads.h on MinGW32/64, it gets in the way.
+ Use mmap(2) for buffers and system malloc for MinGW32/64.
+
+2014-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Merge from gnulib, incorporating:

+ * lib/openat-proc.c: Update from gnulib.
+
+2014-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix port to 32-bit AIX (Bug#17540).
+ * configure.ac (opsys): On Power Architecture, treat release 7 of
+ AIX like releases 5 and 6.
+
+2014-05-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove dependencies on getdelim and getline.
+ * configure.ac (getdelim, getline): Remove.
+
+2014-05-18 Glenn Morris <rgm@gnu.org>
+
+ * configure.ac: Do not bother testing for png in non-graphical builds.
+
+2014-05-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ Port ctags+etags build to Sun C 5.12.
+ * .bzrignore: Remove lib-src/ctags.c.
+
+ Port recent libpng changes to hosts with missing png.h.
+ * configure.ac (HAVE_PNG): Port to platforms where libpng-config
+ succeeds but png.h is absent, by testing libpng-config's output
+ rather than trusting it. I ran into this problem when building
+ Emacs trunk on a Solaris 10 host.
+
+2014-05-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ Assume C99 or later (Bug#17487).
+ * lib/stdarg.in.h, lib/stdbool.in.h, m4/stdarg.m4, m4/stdbool.m4:
+ Remove.
+ * configure.ac (_AC_PROG_CC_C89): Define a dummy, to keep 'configure'
+ smaller.
+ (gl_PROG_CC_C99): Use this to get C99 or later.
+ * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
+
+2014-05-16 Paul Eggert <eggert@cs.ucla.edu>
+
+ Don't require pkg-config when building from repository.
+ * INSTALL: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
+ * INSTALL.REPO: pkg-config is no longer required to build from
+ the repository.
+ * autogen.sh: Don't check for pkg-config.
+ (progs): Remove pkg-config.
+ (pkg_config_min, AUTORECONF_ENV, env_space, ACLOCAL_PATH):
+ Remove. All uses removed.
+ * m4/pkg.m4: New file, built by admin/merge-pkg-config.
+ * configure.ac: Remove unnecessary m4_pattern_forbid of ^PKG_ and
+ an AC_ARG_VAR of PKG_CONFIG_PATH. pkg.m4 does that for us.
+ (EMACS_CHECK_MODULES): Remove workaround for old pkg-config bug,
+ as we use pkg.m4 from a newer pkg-config.
+
+2014-05-15 Jan Djärv <jan.h.d@swipnet.se>
+
+ * configure.ac (LIBPNG): Do not test for libpng if NS_IMPL_COCOA.
+
+2014-05-13 Dmitry Antipov <dmantipov@yandex.ru>
+
+ * configure.ac (HAVE_XFIXES): Define if available.
+ (XFIXES_CFLAGS, XFIXES_LIBS): New AC_SUBSTs.
+ (--enable-link-time-optimization): Add clang support.
+ * INSTALL: Mention it.
+
+2014-05-12 Katsumi Yamaoka <yamaoka@jpl.org>
+
+ * configure.ac (EMACS_CHECK_MODULES): Fix typo in previous change.
+
+2014-05-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ Work around bug in pkg-config before 0.26 (Bug#17438).
+ * configure.ac (EMACS_CHECK_MODULES): Check for failed exit status
+ of pkg-config, on older pkg-config versions that don't do it
+ properly.
+
+2014-05-07 Glenn Morris <rgm@gnu.org>
+
+ * autogen.sh: Check for failing aclocal.
+
+2014-05-05 Glenn Morris <rgm@gnu.org>
+
+ * autogen.sh: Check any pre-existing ACLOCAL_PATH.
+
+2014-05-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ Consult libpng-config more consistently (Bug#17339).
+ This is mainly for simplicity, but it should also avoid
+ some future problems like the ones we recently had with NetBSD.
+ * configure.ac (LIBPNG): Configure after LIBZ. Use libpng-config
+ for cflags, too. Append -lz if we're not already doing that with
+ LIBZ. Do not bother appending -lm, since we always append that.
+ Coalesce some duplicate code.
+
+ * autogen.sh: Use ‘"’ to quote a message that often contains ‘'’.
+
+ Require ImageMagick >= 6.3.5, due to PixelSetMagickColor (Bug#17339).
+ * configure.ac (IMAGEMAGICK_MODULE): Bump prereq from 6.2.8 to 6.3.5.
+ A more-complicated fix would be to remove uses of PixelSetMagickColor,
+ introduced in ImageMagick 6.3.5 (Sept. 2007).
+
+2014-05-04 Glenn Morris <rgm@gnu.org>
+
+ * configure.ac (LIBPNG): Consult libpng-config for the precise
+ form of "-lpng" to use. (Bug#17339)
+
2014-05-03 Glenn Morris <rgm@gnu.org>
* autogen.sh: If all else fails, try using pkg-config to find pkg.m4.
