|  | *	- Verify & Check all calls for correctness | 
|  | *	  (currently only WSAGetHostByName*, WSAGetServByPort* calls) | 
|  | *	- Check error returns. | 
|  | *	- mirc/mirc32 Finger @linux.kernel.org sometimes fails in threaded mode. | 
|  | *	  (not sure why) | 
|  | *	- This implementation did ignore the "NOTE:" section above (since the | 
|  | *	  whole stuff did not work anyway to other changes). |
