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.
