Enclose defintions of INVALID_SOCKET, SOCKET_ERROR, closesocket, ioctlsocket...

Enclose defintions of INVALID_SOCKET, SOCKET_ERROR, closesocket, ioctlsocket between #ifndef/#endif (they are coming from _WIN32 and CASTOR is not the only package trying to mimic _WIN32 with #define hacks - an example is gsoap and its redefinition of closesocket [btw gsoap should have protected his definition as well...])
