wine users - Oct 2009 - wine and multicast socket

I have an application, and when run, it gives these errors :-

fixme:winsock:_remap_optname Unknown optname 10, can't remap!
fixme:winsock:_remap_optname Unknown optname 12, can't remap!
fixme:winsock:ws_sockaddr_ws2u Unknown address family 56574, return NULL.

fixme:winsock:ws_sockaddr_ws2u Unknown address family 23643, return NULL.
fixme:winsock:ws_sockaddr_ws2u Unknown address family 717, return NULL.

I believe it is because the application listens to muticast socket and that
seems to fail under wine. I am running wine 1.1.26.

Rdgs

It seems that there were a patch for wine to have multicast, may I know if the
patch has been included into wine ?
