Modified files:
	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.
