What does the C standard say about the physical size of an int in bits, 
versus the largest and smallest integer that can be held in those bits?
Consider a 64 bit int which is a simple degenerate floating point number 
with 16 bits of mantissa (presumably set to 0) and 48 signed bits of 
mantissa.  All math done in unnormalized floating point.

Does C require 1's or 2's complement or can it support sign-magnitude
