+ doc: clean up quotation style in NEWS.
+ * NEWS (2.5): For multi-character tokens in example grammar rules,
+ use "token" not 'token'. In English, use a consistent quotation
+ style; we might as well follow the precedent seen in info pages:
+ `quote' not "quote".

+ tests: pacify gcc 4.6.0's -Wunused-but-set-variable.
+ Reported by Jim Meyering at
+ <http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>.
+ * tests/actions.at
+ (Default %printer and %destructor for mid-rule values): Define
+ YYLLOC_DEFAULT so that it uses its Rhs argument.
+
+2011-04-16 Joel E. Denny <joeldenny@joeldenny.org>
+
+ 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.
+
+2011-04-09 Joel E. Denny <joeldenny@joeldenny.org>
+
+ Fix missing updates to GPLv3.
+ Reported by Tys Lefering at

+
+ 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.
+
+2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>
+
+ Pacify maintainer-check-posix.
+ Adding command-line options after the grammar file name is not
+ permitted, so disable checks that do that when
+ maintainer-check-posix is running.
+ * tests/local.at (AT_BISON_CHECK_NO_XML): Don't run the
+ problematic checks when POSIXLY_CORRECT=1. Also, for readability,
+ remove an unnecessary m4_if.
+
+2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>
+

+ Reported by George Neuner at

+ (warnings_args, warnings_types): Add entry for warnings_other.
+ (usage): Update.
+ * src/getargs.h (enum warnings): Add entry for warnings_other.
+ * src/gram.c (grammar_rules_useless_report): If -Wno-other, then
+ don't print useless rules.
+ * src/reader.c (symbol_should_be_used): Rather than adjusting the
+ return value based on whether midrule value warnings are enabled,
+ accept a new parameter for telling the caller whether true is
+ being returned for a potential midrule warning.
+ (grammar_rule_check): Use midrule_value_at for midrule value
+ warnings, and continue to use warn_at for all other warnings. Let
+ them check whether the warnings are enabled.
+ * tests/local.at (AT_BISON_CHECK): Update documentation.
+ (AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none
