Under mingw we have the windows' networking aka winsock that's not 1:1 
compatible to the BSD sockets. We should include 'winsock.h' rather than 
'socket.h'; we have to call WSAStartup() first; a bit different socket
options, datatypes, etc...

May be that's reason to have networking disabled and don't bother with
