iTunes and other Apple software on Windows runs with code that looks pretty much exactly like that. Those code bases are compiled from Obj-C into plain C by the objc rewriter module in clang, then compiled into machine code by Visual Studio. You can take a look at what the clang rewriter does here: http://clang.llvm.org/doxygen/RewriteObjC_8cpp_source.html
That's very interesting, I've never heard of that (but assumed it would be something pretty much along those lines).
What's the Obj-C runtime used on Windows for those apps? Is it a descendant of the NeXT runtime which did run on Win32 at one point, or something else?
