We are talking about a macro here, first of all. Not a function.

Second of all, C++ headers are cerrno, and things like cstdarg, which 
explicitly put into namespace std::. The C compatibilty headers are things like 
stdarg.h, that inject the std names into the global namespace.

I consider this issue resolved.
