	I understand the problem.  To do this, we need to implement
	another nsdispatch() variant, and call that from getaddrinfo().
	As *BSD uses different version of BIND resolver, I don't think
	KAME team can maintain that code...
	(nsdispatch() is only in netbsd, IIRC)

	If we do the above, I would like to make it possible to put
	extended IPv6 scoped address notation (de0%fe80::1) into /etc/hosts.
	This requires that resolver use sockaddr as basic type, not in{,6}_addr.
