--- Comment #10 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I have found the origin of the problem. It is due to
#include <stdlib.h>
which after some steps include
sys/cdefs.h
which contains the following lines
/*
* We use `__restrict' as a way to define the `restrict' type qualifier
* without disturbing older software that is unaware of C99 keywords.
*/
#if __STDC_VERSION__ < 199901
#define __restrict
#else
#define __restrict restrict
#endif
Note that using something such as -D__STDC_VERSION__=201401 gives a lot of
errors of the kind
/usr/include/stdlib.h:154:51: error: conflicting types for 'restrict'
size_t mbstowcs(wchar_t * __restrict , const char * __restrict, size_t);
I don't have any idea about the best way to fix it.
