+	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.
