By my recollection (going back to the PDP-11 days) is that an int has to 
be able to hold a pointer (a dreadful mistake, IMHO), and a long has to be 
at least the size of an int; oh, and a char had to be at least the size of 
a byte.  Fun times, swapping programs between the Cyber and the PDP... 
Great fun, for certain definitions of fun, that is.

I'd like to see your counter-example.
