Just as a warning, I don't think anyone has gotten the 
mingw/clang/libobjc2/gnustep combo to work before, so it'll likely involve a 
bit of work. The other option is gcc 4.6, which supports @property and most 
ObjC 2 features, excluding blocks. I'm not sure if anyone has successfully used 
this with gnustep on windows either.

When mingw does a release with gcc4.6 or clang, it should be easy for us to 
make an installer where ObjC2 works out of the box.

I don't think so, but we should have that :-)

On windows, if you use gcc or clang you are stuck with SJLJ exceptions 
(setjmp/longjmp). I think implementing support for Window's native SEH is on 
both gcc's and clang/llvm's wish list.
