Speaking of which, SourceForge seems like the ideal way to build
nightly Winetests by using their compile farm.  I've been trying
to get access to it for a few days in order to figure that out.  
All of the pieces seem to fit together and the only unknown is
whether or not they have mingw on their servers.  Does anyone
else have any suggestions how we could create nightly builds?
