IPv6 cleanup patch needs testers

I've prepared a patch that cleans up the current #ifdef HAVE_IPV6 mess by
supplying a substitute getaddrinfo() function (with limited capabilities)
if the real one is missing. Could someone test it on a machine without
getaddrinfo() and/or IPv6?

(run autoconf before you reconfigure)
