Non-Blocking Connection is not working under WIN32 build of PGSQL interface.
I Spend some time to make it work.
Here is changed fe-connect.c
I did not check if all of non-blocking functions are working,
but I checked PQsetnonblocking,PQisnonblocking,
PQsendQuery, PQgetResult and few others.
Can Anyone check my corrections and try to built this functionality
in future versions ?
Thanks !
