I do not own, nor have I read, a copy of the ANSI standard.  That said,
ints in my experience have 'special status' in that it is usually the
machine word size, sort of like an atomic data unit, whereas shorts
are an artificial construction.  Even though the two have the same size
in the example, this may nevertheless influence the behavior of the
compiler.
