+
+       * src/scan-gram.l: Add %option nounput, since we no longer use unput.
+       (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+       Do not insert the expected token via unput, as this runs afoul
+       of a POSIX-compatibility bug in flex 2.5.31.
+       All uses changed to BEGIN the parent state,
+       since we no longer insert the expected token via unput.
+       * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+       that is no longer emitted after the above change.
+
+       * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+       the first one.  This change is from Paul Hilfinger, and it fixes
+       regression reported by Werner Lemberg in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+       (resolve_sr_conflict): Don't invoke state_errs_set
+       unless one or more tokens have been explicitly made errors.
+       Otherwise, the above change causes Bison to abort.
+
+       * tests/existing.at (GNU pic Grammar): New test case, taken from
+       Lemberg's email.
