Yvan, this is the official way to fix it. IPv6 requires usage of
sockaddr_storage instead of sockaddr (which was the IPv4 time standard).
They changed the name to keep binary compatibility. Who ever added the
IPv6 stuff to that func was missing the conversion of sockaddr.
So yes, this is the correct thing to do.
