this isn't quite correct. If you look carefully he is running
into the problem where some past programmer of the code he is
now working on, typedef'ed the struct sockaddr_un to be SOCKET
which in the windows world is the socket descriptor returned from
a socket() call. He also needs to change his code over to use
named pipes/unix domain sockets.
