The problem with bind is that the resolver library doesn't work correct,
I have problems using it for an Exim port, i.e. the service lookup in
/etc/services doesn't work so it wouldn't help much to have it.
I have also problems using nslookup, maybe it is the same cause.

That is the point, winsock is there and needs only to be accessed.
What we need is a wrapper around winsock.  So the unix apps can call
their res_query or whatever from libresolv which is in fact winsock.
