Apparently this is the problem:

> _Noreturn void     abort(void);
> // [...] more declarations
> _Noreturn void     exit(int);

Those noreturns are supposed to be written with GCC syntax and this can 
be workarounded with this :

> |#define _Noreturn __attribute__ ((noreturn))|
|
Maybe the compiler can be checked in preprocessor and add that compatibility line so the code compiles correctly
||Any opinion on this?|

Thanks for your time and for reading !
