[PATCH] Implement new hook for max_align_t_align

Hi,

I think your callback should also directly control the
alignment of max_align_t in stddef.h:

typedef struct {
   long long __max_align_ll __attribute__((__aligned__(__alignof__(long 
long))));
   long double __max_align_ld 
__attribute__((__aligned__(__alignof__(long double))));
   /* _Float128 is defined as a basic type, so max_align_t must be
      sufficiently aligned for it.  This code must work in C++, so we
      use __float128 here; that is only available on some
      architectures, but only on i386 is extra alignment needed for
      __float128.  */
#ifdef __i386__
   __float128 __max_align_f128 
__attribute__((__aligned__(__alignof(__float128))));
#endif
} max_align_t;


otherwise these will not match.


Bernd.
