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.
