Windows.h and clang (LLVM)

I am trying to compile a small project that includes windows.h using the clang compiler. Unfortunately, clang produces some errors that I cannot solve. What causes these errors? Does clang not support all the necessary functions, am I missing something?

Perhaps you need to define a clang-compatible version of the UNREFERENCED_PARAMETER macro. Something like this should help you along the way: https://web.archive.org/web/20130425151054/http://sourcefrog.net/weblog/software/languages/C/unused.html
