The /only/ assumptions you may legitimately make are those encoded in the C
language spec: sizeof (char) <= sizeof (short) <= sizeof (int) <= sizeof
(long) <= sizeof (long long). But "<=" means less than OR equal, and you
can't assume /which/ of those two.

It's worked in the past. But now there are 64-bit platforms in common use
and we all have to be aware.
