That's a 64-bit unsigned long long constant equal to 1. I need that to
be able to shift left by 32; if it were just the 1UL it would fall off
the end.

No, you inadvertently found a bug in my code anyway, so thanks.
After going through the work of creating a 64-bit value, I was
immediately casting it to 'int'. It's been fixed. The joys of having
ones "intermediate work product" on display for the world :-)
