Well, I looked at it and (without optimizing) the first case was "quicker".
I was using the UNIX SVR4 C compiler. If your compiler has an assembly option,
(-S in Johnson's PCC) use it to see for yourself.
When I optimize, my compiler shows no difference. So there you have it,
it sort of just depends on what you're using at the time.
