+       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.
