* - Add WSACancel* and correct handle management. (works rather well for

|
|
* - 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).
