Not really.  There is nothing except a few CPU cycles preventing a 32-bit system 
manipulating a 64-bit integer.  In the C99 C standard it's called a long long 
int.  For time/clock, it probably should be unsigned.

As I said earlier, I see 32-bit systems fading away, but not for technical 
reasons.  It's easier and cheaper to make all 64-bit CPUs instead of mixed 
32-bit and 64-bit, so they'll all go to 64-bit systems.  There is nothing really 
wrong with 64-bit systems, it's just that they're rarely needed.
