Sorry. I forgot that I'm actually using LoadLibrary here. But,
$ cygcheck ./wpcap.dll
So the dependency comes from winsock? It doesn't sound like that is
avoidable? That pthreadVC.dll is a bit scary too.
Also, the app in question uses a tiny portion of the ddraw.dll, which also
depends on msvcrt.dll. I can't believe *this* is really not supported.
