Fix function declaration

We almost never encounter it, so this error has gone undetected
for quite some time. When the system lacks a sockaddr structure,
we have to provide a "no-op" function. What remains unclear is
how that can compile when the function parameters include a
sockaddr structure - but that mystery will have to remain
unsolved.
