Yeah whatever, you did something that I didn't spare the brain cell to
try to figure out back then :-) Maybe I should have ... I was also
worried about the embedded folks having a go at me for "bloat they don't
need". But in the end it was wrong, it should always be 64-bit.

But regardless, I still think it should be a specific type. "unsigned
long long" really sucks.

Cheers,
Ben.
