+
+        Improve robustness of 'make bootstrap' (Bug#12376).
+        Run autogen.sh after bootstrap-clean, to avoid bzr pull issues.
+        * INSTALL, README: Document autogen.sh.
+        * Makefile.in (Makefile): Mark it as precious, since it's updated
+        atomically.
+        (MAKE_CONFIG_STATUS): New macro.
+        (config.status, bootstrap): Use it.  This causes 'make bootstrap'
+        to run config.status with the --recheck option, which is more
+        appropriate for a bootstrap.
+        (bootstrap): Run autogen.sh right after cleaning.  Don't worry
+        about failures due to missing tools.
+        * autogen.sh: Exit with status 101 when failing due to missing tools.
+        * make-dist: Distribute autogen.sh.

+
+        Assume C89 or later for math functions (Bug#12381).
+        * configure.ac (frexp, fmod): Remove checks for these functions,
+        as we now assume them.
+        (FLOAT_CHECK_DOMAIN, HAVE_INVERSE_HYPERBOLIC, NO_MATHERR)
+        (HAVE_EXCEPTION):
+        Remove; no longer needed.

+
+        More signal-handler cleanup (Bug#12327).
+        * configure.ac (FLOAT_CHECK_DOMAIN): Comment fix (Bug#12327).
+
+2012-09-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Signal-handler cleanup (Bug#12327).
+        * configure.ac (PTY_OPEN, PTY_TTY_NAME_SPRINTF):
+        Adjust to syssignal.h changes.
+        (SIGNAL_H_AB): Remove; no longer needed.
+
+2012-09-04  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Simplify redefinition of 'abort' (Bug#12316).
+        * configure.ac (NO_ABRT): Remove.
+
+        * configure.ac (_setjmp, _longjmp): Check by compiling
+        instead of by guessing.  The guesses were wrong for
+        recent versions of Solaris, such as Solaris 11.
+
 2012-09-03  Paul Eggert  <eggert@cs.ucla.edu>
 
+        * configure.ac (WARN_CFLAGS): Omit -Wjump-misses-init.
+        It generates false alarms in doc.c, regex.c, xdisp.c.  See
+        <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00040.html>.

         Merge from gnulib, incorporating:
