win32 socket definition

The win64 port has showed that we have two sockets declared
incorrectly. They are supposed to be declared as SOCKET on win32, but
they are declared as int. See attached patch.

Given that SOCKET is actually defined as int on win32 (no warnings or
anything there, just on win64), I'm inclined to apply this patch just
to HEAD and not bother with backpatching.

Comments?
