Given that YYERROR_VERBOSE doesn't require any changes in the way the
parser is called, unless defining it causes problems with YACC or BYACC
parsers, it's probably worth enabling it even if YACC *doesn't* do
anything better if it's defined (unless it does something worse if it's
defined; I'll check to see, on my Solaris partition, if YYERROR_VERBOSE
affects the behavior of YACC).
