+       Avoid warnings generated by GCC 2.95.4 when Bison is
+       configured with --enable-gcc-warnings.
+       * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
+       yy::]b4_parser_class_name[::translate_,
+       yy::Stack::operator[] (unsigned),
+       yy::Stack::operator[] (unsigned) const,
+       yy::Slice::operator[] (unsigned),
+       yy::Slice::operator[] (unsigned) const):
+       Rename local vars to avoid warnings.
+       * tests/glr-regression.at (Improper handling of embedded actions
+       and $-N in GLR parsers): Remove unused local variable from yylex.
+       * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
+       (void) as arg when not pure, since we now assume C89 when building
+       Bison.  Pacify GCC by using parameter.
