  24  * FIXME:

  27  *      - Verify & Check all calls for correctness
  28  *        (currently only WSAGetHostByName*, WSAGetServByPort* calls)
  29  *      - Check error returns.
  30  *      - mirc/mirc32 Finger @linux.kernel.org sometimes fails in threaded mode.
  31  *        (not sure why)
  32  *      - This implementation did ignore the "NOTE:" section above (since the
