+       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.

+       Add -Wother so -Wnone suppresses all warnings.
+       Reported by George Neuner at
+       <http://lists.gnu.org/archive/html/bug-bison/2010-08/msg00002.html>.
+       * NEWS (2.5): Document.
+       * THANKS (George Neuner): Add.
+       * doc/bison.texinfo (Bison Options): Document.
+       * src/complain.c, src/complain.h
+       (warn_at, warn_at_indent, warn): Suppress warning if -Wno-other.
+       (midrule_value_at): New warning function, similar to yacc_at in
+       that it's controlled by its own warning category.
+       * src/getargs.c (warnings_flag): Initialize to warnings_other.
+       (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
+       disable all warnings exercised in the test suite.

        Don't let -Wnone disable -Werror.
