+
+ * configure.ac: Warn about --enable-link-time-optimization's issues
+ in --help message (Bug#17806).
+
+ Port to GCC 4.9.0 with link time optimization (Bug#17806).
+ * configure.ac (CFLAGS): With link time optimization,
+ use -ffat-lto-objects if supported; otherwise Emacs won't
+ build with GCC 4.9.0.

+2014-06-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ Port part of the AIX fix to Solaris (Bug#17598).
+ * configure.ac (_REENTRANT): Define on Solaris if HAVE_PTHREAD.
+ This ports part of the recent AIX fixes to Solaris. It is needed
+ for the same reason that _THREAD_SAFE is needed on AIX, e.g., to
+ make sure that each thread has its own 'errno'.

+2014-06-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ Backport fcntl.h AIX fix from the trunk (Bug#17598).
+ This fixes a bug with the shell freezing. See:
+ http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17598#185
+ Merge from gnulib, incorporating:
+ 2014-05-31 dup2, fcntl, fcntl-h: port to AIX 7.1
+ * lib/fcntl.in.h, m4/dup2.m4, m4/fcntl.m4:
+ Update from gnulib.
+
+2014-06-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ Port better to AIX (Bug#17598).
+ * configure.ac (with_xpm_set): New shell var.
+ (_THREAD_SAFE): Define on AIX if HAVE_PTHREAD.
+ (with_xpm): Default to 'no' on AIX.
+ (LIBXPM): Append -lXpm if -lXaw is also used, as the latter
+ requires the former on AIX.
+
+2014-05-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ 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.
+
+2014-05-22 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.

+
+ * configure.ac (INSTALL_INFO):
+ Revert to just checking for "install-info".
+
+2014-05-17 Glenn Morris <rgm@gnu.org>
+
+ * configure.ac (INSTALL_INFO): Try the identical-but-quieter-on-Debian
+ "ginstall-info" before "install-info".
