All of these are checked with IPv4/IPv6 kernel and IPv4 only kernel.

itojun> ume, you really want to look at the latest kame libineet6/resolv/.

I read your commit message of KAME CVS.  Then, I had look around
resent res_init.c and res_send.c of kame/libinet6, and changed the
code.  I believe I already mereged corresponding code.  If I forgot to
merge the part should be merged, please tell me.  Thanks.

I just tried nslookup/dig/host of WC-CDROM 4.0-RELEASE live filesystem
with IPv4/IPv6 kernel and IPv4 only kernel,  and it seems working.
