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.
