H A Dstdnoreturn.hdiff 229437 Tue Jan 03 23:16:36 MST 2012 ed Simply disallow <stdnoreturn.h> to be used in combination with C++.

There is no way one could possibly use this header file in combination
with C++ code. The problem is that in C11 the `noreturn' macro expands
to the `_Noreturn' function specifier, while in C++11 the `noreturn'
keyword is an attribute.

So in C11 you have to write:

noreturn void exit(int status);

While in C++11 you have to write:

[[noreturn]] void exit(int status);

It is impossible to #define noreturn for C++ in such a way that it
allows both conventions.

By intentionally breaking this header this way, we prevent people from
using this header in their C++<11 sources.
