+       glr.c: omit yyresolveLocations when locations are disabled.
+       This prevents gcc 4.6.0's -Wunused-but-set-variable from warning
+       about yyresolveLocations's local yyrhsloc.  When locations are
+       enabled, there's no such warning because YYLLOC_DEFAULT then uses
+       yyrhsloc.  Reported by Jim Meyering at
+       <http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>.
+       * data/glr.c (yyresolveLocations): Omit definition when locations
+       are disabled.
+       (yyresolveValue): Omit yyresolveLocations invocation when
+       locations are disabled.

+       gnulib, autoconf: update.
+       * README-hacking (Updating a submodule): Give advice on how to
+       determine the versions of gnulib and autoconf to which we should
+       update.
+       (Release Procedure): Note that submodules should be updated.
+       * bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as
+       suggested in updated gnulib NEWS.
+       * gnulib: Choose a stable snapshot according to advice in Bison's
+       README-hacking.
+       * po/POTFILES.in (lib/pipe.c): Rename to...
+       (lib/spawn-pipe.c): ... this.
+       * src/output.c: Update to include spawn-pipe.h.
+       * submodules/autoconf: Update to latest for improvement in m4.m4
+       that excludes M4 with buggy strstr.  The only other changes to
+       files that we use are copyright updates.

+       Add -Wconflicts-sr and -Wconflicts-rr.
+       Thus, conflict reports are now affected by -Werror and -Wnone
+       (unless %expect or %expect-rr is specified).  Reported by George
+       Neuner at
+       <http://lists.gnu.org/archive/html/bug-bison/2010-08/msg00002.html>.
+       * NEWS (2.5): Document.
+       * doc/bison.texinfo (Bison Options): Document.
+       * src/complain.c, src/complain.h (set_warning_issued): Export
+       function.
+       * src/conflicts.c (conflicts_print): Suppress conflict report
+       based on -Wno-conflicts-sr and -Wno-conflicts-rr, and treat
+       conflicts as errors if -Werror.
+       * src/getargs.c (warnings_flag): Initialize with
+       warnings_conflicts_sr and warnings_conflicts_rr as well.
+       (warnings_args, warnings_types): Add entries for
+       warnings_conflicts_sr and warnings_conflicts_rr.
+       (usage): Update.
+       * src/getargs.h (enum warnings): Add entries for
+       warnings_conflicts_sr and warnings_conflicts_rr.
+       * tests/conflicts.at (-W versus %expect and %expect-rr): New test
+       group.
+       * tests/local.at (AT_BISON_CHECK_NO_XML): Update now that the
+       conflict report can produce a "warnings being treated as errors"
+       message.  Also, check that stderr is now fully scrubbed by -Wnone
+       when the exit status is 0.
