	ume, you really want to look at the latest kame libineet6/resolv/.
	the code is much more conservative about backward compatibility
	(selecting _res.nsaddr_list and _res_ext.nsaddr_list).

	make sure to check if nslookup/dig/host work right.  they touch
	struct _res directly and will make it a good torture-test for backward
	compatibility
	(not sure if freebsd nslookup uses libc resolver at all).
