Subject: Add -Wconflicts-sr and -Wconflicts-rr.
X-Git-Tag: v2.5_rc1~8
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/6f8bdce25df5669b0b200c2a3848a1c08a44eb79?hp=6f8bdce25df5669b0b200c2a3848a1c08a44eb79

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>.

* src/conflicts.c (conflicts_print): Suppress conflict report
based on -Wno-conflicts-sr and -Wno-conflicts-rr, and treat
conflicts as errors if -Werror.

warnings_conflicts_sr and warnings_conflicts_rr as well.

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.
