Hi,

afaik that's a missing #ifdef in "driver_ndis_.c". The bug can be fixed
as described on http://www.codealias.info/technotes/wpaw32compile :

+#ifdef CONFIG_NDIS_EVENTS_INTEGRATED

   void wpa_driver_ndis_event_pipe_cb(void *eloop_data, void *user_data)
   {
  @@ -106,3 +107,5 @@
                             (int) GetLastError());
          }
   }
+
+#endif
