It's possible. Integer promotion rules say that only types of rank lesser than
int can promote to int and only so long as all the values of that integer fit
int, otherwise they promote to unsigned. Therefore, you'd need to find a
platform where

  sizeof(size_t) < sizeof(int)

That is permitted, but I don't think exists or has ever existed.
