Modified files:
	data           : yacc.c 

Log message:
	(yyparse): New local var yylerrsp, to record the
	top of the location stack's error locations.
	(yyerrlab): Set it.  When discarding a token, push its location
	onto yylerrsp so that we don't lose track of the error's end.
	(yyerrlab1): Now is only the target of YYERROR, so that we can
	properly record the location of the action that failed.  For GCC
	2.93 and later, insert an __attribute__ ((__unused__)) to avoid
	GCC warning about yyerrlab1 being unused if YYERROR is unused.
	(yyerrlab2): New label, which yyerrlab now falls through to.
	Compute the error's location by applying YYLLOC_DEFAULT to
	the locations of all the symbols that went into the error.
