I was looking at it from the point of view that the "%I64u" format is incorrect, though it works and perl's own implementation of formatted output emulates it.

If I could be sure old MSVCRT supported "%llu" I'd make a PR switching it to the standard form, since it would let us turn on -Wformat and better detect format issues on the specialness that is Win32. And reduce confusion from people wondering what this I64 format business is.
