You cannot.  It's a public header and it does not (and should not) define
any of the AF-specific struct sockaddr_foo types.  I don't think this
interface can be used in a strictly standard-C-compliant fashion.  We need
to come up with an idiom or helper code to facilitate using it in whatever
fashion is closest to compliant and is in fact thoroughly safe.  Maybe Paul
has some ideas.
