The code I'm staring at should bind both and should even bind
multiple addresses if the hostname resolves to multiple addresses.
What do you have for inet_protocols?
The key question is whether getaddrinfo() on your system returns
multiple addresses for the host, or just one.
What's in /etc/host.conf (Linux?) you'll "multi on" if the hostnames
are in /etc/hosts...
