Very much disagree with your point about constraints. A bug existing in 10+ year old code that has never really been tested and run by four people doesn't support any point. In real life one actually checks these things, it's not that complex :) Case in point: counting the f's in your constants took me longer than finding that constraint bug did. You would argue ULLONG_MAX would fix that, I suppose. You're right, that's the 32-bit arm instruction, doh. In my defense, this code was written before 64-bit ARM existed!
