I have done exactly that. I assume fcntl(), ioctl(), select() use errno
even if used on a socket, while getsockopt(), setsockopt(), socket(),
connect(), getsockname(), send(), recv() use WSAGetLastError. Is this
list correct?
The patch is attached. Please let me know so I can finalize it and
apply it.
