Update.

2004-06-27  Ulrich Drepper  <drepper@redhat.com>

	* resolv/resolv.h (RES_NOIP6DOTINT): Define.
	* resolv/res_init.c (res_setoptions): Handle no-ip6-dotint option.
	* resolv/gethnamaddr.c (gethostbyaddr): Don't lookup with .ip6.int
	if RES_NOIP6DOTINT flag is set.
	* resolv/nss_dns/dns-host.c (_nss_dns_gethostbyaddr_r): Likewise.
