Well that's what I would have thought it was.  All the PC compilers that
I have used so far (Borland + Topspeed) have int as 16bit. But when
I was looking up the size of short int in limits.h, int was right
next it. And the limit for signed int was +/- 2billion or so. I believe
the size of int is compiler specific, not platform specific.
