Hmph, this is simpler but it does not report all errors any more.
So it would be better to do:

	int err = 0;

	for (; opts->type != OPTION_END; opts++) {
		if ((opts->flags & PARSE_OPT_LASTARG_DEFAULT) &&
		    (opts->flags & PARSE_OPT_OPTARG))
			err |= optbug(opts, "uses incompatible flags "
						"LASTARG_DEFAULT and OPTARG");
	}
	if (err)
		exit(128);

Sorry about that.
