* fhandler_socket.cc (fhandler_socket::recvfrom): Initialize res to

	SOCKET_ERROR.  Use SOCKET_ERROR instead of -1 throughout.
	(fhandler_socket::recvmsg): Ditto.
	(fhandler_socket::sendto): Ditto.
	(fhandler_socket::sendmsg): Ditto.
	* net.cc (wsock_event::prepare): Call WSASetLastError instead of
	SetLastError.
	(wsock_event::wait): Use SOCKET_ERROR instead of -1.
