Summary: Broadcast messages slightly broken in winsock
           Product: Wine
           Version: 0.9.30.
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-net
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Something is still not correct in the way we enumerate interfaces in winsock. I
was playing StarCraft yesterday with some friends via a VPN in LAN mode, and
while I could get direct messages to the game host, I couldn't see the messages
other players sent and they couldn't see mine. I assume I could only see the
game host because we were in the same LAN, I need to check that.

As I'm seeing somewhat similar problems when doing broadcasts to my dplay test
VMs, I assume this is due to "all interfaces" broadcast messages only being sent
via the primary interface.
