I booted into Windows today and figured it would be a good idea to try corebase there. I ran into some problems that I was able to fix, but I don't know what to do with the set of error I'm getting now. It's about BOOL being defined by both windef.h and objc/objc.h. I'm sure I'm screwing something up, can anyone more familiar with Windows please shed some light? I've attached the output.
