-/* Return 1 if an array of N objects, each of size S, cannot exist due
- to size arithmetic overflow. S must be positive and N must be
- nonnegative. This is a macro, not an inline function, so that it
- works correctly even when SIZE_MAX < N.
-
- By gnulib convention, SIZE_MAX represents overflow in size
- calculations, so the conservative dividend to use here is
- SIZE_MAX - 1, since SIZE_MAX might represent an overflowed value.
- However, malloc (SIZE_MAX) fails on all known hosts where
- sizeof(ptrdiff_t) <= sizeof(size_t), so do not bother to test for
- exactly-SIZE_MAX allocations on such hosts; this avoids a test and
- branch when S is known to be 1. */
