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.
