Yeah, this comes up every few weeks.  Fix pushed.

Yeah, half way to correct.  The rest is to cast "i + 1" to (unsigned long
long).

Yup.  We go around in curcles on this, but we keep coming back to
forcing size when we need to, then casting to something overly large
for printf(). The POSIX macros (PRIu64) do not work a lot of places.

Yeah.  A lot of the embedded guys, and Access Points (OpenWRT, etc.) are
stuck in 32-bit land.  Oh, and Raspbian, of course.
