No more support for Microsoft's best OS?

bitcoin fails with something like "couldn't find freeaddrinfo in WS2_32.DLL"

Ok, I put in a ws2_32.dll from an xp-install in my bitcoin.exe directory, then it complained about ntdll.dll, and I put that in there, to no avail. I don't really feel like replacing a lot of dll's in my system from various sources.

I wonder if this is a build issue or if something changed in the code to make W2k obsolete. I might try to build it from source, but for now I'm just going back to 0.3.20.2
