+       Revert 2009-12-30 change for undefined %prec token complaints.
+       That is, keep them as warnings because that should be sufficient
+       to satisfy POSIX without creating backward compatibility issues.
+       Suggested by Richard Stallman at
+       <http://lists.gnu.org/archive/html/bison-patches/2010-03/msg00033.html>.
+       * NEWS (2.5): Remove mention of complaint.
+       * src/reader.c (grammar_rule_check): Convert warning back to
+       complaint.
+       * tests/input.at (%prec's token must be defined): Update.
