        data           : yacc.c 

Log message:
        (YYERROR): Now just 'goto yyerrorlab', since the
        macro's size was becoming unwieldy.
        (yyerrlab): Do not discard an empty lookahead symbol, as this
        might destroy garbage.
        (yyerrorlab): New label, with the old contents of YYERROR,
        plus the following change: pop the stack of rhs corresponding
        to the production that invoked YYERROR.  That is how Yacc
        behaves, and POSIX requires this behavior.
        (yyerrlab1): Use YYPOPSTACK instead of its definiens.
