Hi,
The reftable patch is starting to shape up, but I still see failures on OSX,
See https://dev.azure.com/gitgitgadget/git/_build/results?buildId=29465&view=logs&j=cfa20e98-6997-523c-4233-f0a7302c929f&t=3de1ae02-4adb-5138-54da-65cec5dd3141&l=518
What is the right incantation to do printf of a uint64_t on OSX ?
Apparently PRIuMAX is to be used for "uintmax_t", and not for "long
long unsigned int".

You could cast it? Grepping around, that seems to be how PRIuMAX is
used:
printf("%"PRIuMAX"\n", (uintmax_t)var);

Looks like the inttypes.h standard has the defines that I want.

Oh, cool. We handle PRIuMAX and PRId64 in compat/mingw.h, but other than
that, it seems we rely on these being available. There's some discussion
in ebc3278665 ("git-compat-util.h: drop the `PRIuMAX` and other fallback
definitions", 2019-11-24).

Yup, that is used already in existing code in our codebase, so it is
just as portable as the rest of Git is ;-)
Thanks.
