It's too much for my taste.
Let's fall back to not providing any struct when namespaces are
important. I.e,. use something like
#ifdef __USE_GNU
struct timespec st_atim;
#else
time_t st_atime;
unsigned long int st_atime_nsec;
#endif
Maybe add || defined __USE_BSD. Depends on what the BSD crowds are
doing and whether it makes sense. We also need a #define
__need_timespec at the top of <time.h> with the same #if expression.
The rationale is that in a POSIX/Unix up you better not depend on
st_atim in the first place, leave alone assigning it to some other variable.
This will avoid the ugly macro business. And yes, defining
st_atime_nsec is perfectly alright. We could consider using
__st_atime_nsec instead to indicate that nobody should use the name.
