Hi Paul,

On MSVC 9, I now get a compilation error:
/home/bruno/msvc/compile cl -nologo -DHAVE_CONFIG_H -I. -I..

Attribut
make[4]: *** [test-stdnoreturn.obj] Error 2
The code in line 371, 372 of stdlib.h contains declarations of 'exit' and
'_exit', with the attribute __declspec(noreturn). Likewise also in
setjmp.h, process.h, and some other .h files.
The current set of definitions
#define _Noreturn __declspec (noreturn)
#define noreturn _Noreturn
leads to a syntax error when someone writes __declspec (noreturn),
because preprocessing transforms it to __declspec (__declspec (noreturn)).
How can this syntax error be avoided?
Bruno
