ikegami most probably wants to point out the fact that, with a 'Q' specifier, 0xFFFF_FFFF will give a different result.

Hm. But that isn't what he said!

What he said was: "your very question demonstrates that -1 and 0xFFFF_FFFF pack differently.". Which is patently and demonstrably wrong.

And I don't see any mention of using OxFFFF_FFFF in conjunction with the Q specifier in Tux post.

Indeed Tux didn't use, nor advocate the use of 0xFFFF_FFFF at all. The whole point of his post was: "Why not simply use -1?" which he demonstrated did the right thing with both 'N' & 'Q'.
