I think that this particular case (using binary libraries with IPv6
enabled on a older libc which doesn't know at all about IPv6) is
probably going to fail in applications too. I'm not sure if
it's worth handling it inside of Xlib. There are enough issues and
separate cases when the libraries are consistent wrt. IPv6 to handle
not to add this additional complexity.
But having said that, your patch seem to handle this particular
situation and since it's the base for your 2nd patch that handles
something more important, I guess both should go in.
