What is your definition of BYTE?
AIUI, the standard (which I don't have a reference to either) guarantees
that `sizeof(char) == 1' but doesn't guarantee that `sizeof(char) ==
8bits'.

AIUI, the standard says short <= int <= long <= long long <= next
generation bit pattern.  Given this the bit length of short, int, long,
long long, ... could all be the same length.

IMO, it would be beneficial for the standard to change to using int8,
int16, int32, etc. so that it was obvious as to what is meant; but, that
isn't likely to happen anytime soon.
