[BZ #4647]
            Tomas Janousek  <tjanouse@redhat.com>
            Ulrich Drepper  <drepper@redhat.com>

	[BZ #4647]
	* resolv/res_send.c (send_dg): Remove socket_pf.  Use ipv6_unavail
	member in __res_state, only convaddr4to6 if nssocks[ns] is a PF_INET6
	socket.
	* resolv/resolv.h (__res_state): Add ipv6_unavail member.  Make
	unused member a bitmap.
	* resolv/res_init.c (__res_vinit): Reset ipv6_unavail if IPv6
	servers are configured.
