btw. is it possible that this is not alligned correctly on sparc64?
should be do something like (not even compile tested)
static void
clear_ad(struct asr_result *ar)
{
struct asr_dns_header h;
memmove(&h, ar->ar_data, sizeof(h));
h.flags = ntohs(h.flags);
h.flags &= ~(AD_MASK);
h.flags = htons(h.flags);
memmove(ar->ar_data, &h, sizeof(h));
}

I'm not entirely sure you are real.
