Efficiently compute aligned pointers to powers of 2 boundaries.

#define ACE_align_binary(ptr, alignment)   ((ptr + ((ptrdiff_t)((alignment)-1))) & (~((ptrdiff_t)((alignment)-1))))
 Return the next integer aligned to a required boundary.
#define ACE_ptr_align_binary(ptr, alignment)   ((char *) ACE_align_binary (((ptrdiff_t) (ptr)), (alignment)))
 Return the next address aligned to a required boundary.
