Log message:
        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>.
        
        (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.
