+       Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
+       GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
+       lookahead symbol, and which sets yychar in parser actions) and it
+       disagreed with the Bison documentation.  This should fix the bug
+       reported by Andrew Walrond in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
+       
+       * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
+       as the caller now does that.
+       (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
+       (YYEMPTY): Parenthesize right hand side, since others use it.
+       (yyparse): Don't assume that our generated code is the only code
+       that sets yychar.
