That's perfectly correct, unless int is narrower than 16 bits on your
platform ;-). Anything narrower than int is implicitly coerced to int
when it's passed to printf. The existence of the h modifier in the
printf format syntax is for scanf, not printf; scanf does have to
know the difference between int and narrower-than-int variables.
