Another thing: I'd appreciate it if someone with
windows downloaded the free Qt SDK (
http://qt.nokia.com/downloads/downloads) and try to compile this project. You can simply open the 'pro' file in Qt Creator that comes with the SDK. The biggest problem is probably the dependencies (openssl, berkelydb/dbcxx) though they likely exist for MinGW already somewhere.
I'm giving that a go now. It may take some time, though...
