Compile errors on Clang-C2

[Kacper_K_]

I am unable to #include <tbb/tbb.h> when compiling with Clang-C2 (Clang with microsoft code-gen) on windows.  I get a multiple errors.  I suspect these errors are most likely due to incorrect platform recognition.  I do not however, get the same errors when compiling with llvm-clang on windows, or any other compiler on windows or linux.

As clang-C2 is far better supported and feature complete it is my only option for clang usage on windows.

Has anyone encountered such an issue before, and if so is there a quick work around?  I am on the latest stable version of tbb interface version 9103.

Here is a sample of the compile errors I see:
