It doesn't look like curl uses this anywhere (anywhere I can find at
least). After some more poking around I notice that the ftp test server
only binds an IPv4 address. We may want to also test with an IPv6
binding as well.

As for the client, it seems to always come up with an IPv4 address, even
if ENABLE_IPV6 is defined. I've been trying to figure out why that is,
but it's kind of a labyrinth in the connect stuff and I'm getting dizzy.
Anyone know where IPV6 is forced (or is it)?
