We handle PRIuMAX and PRId64 in compat/mingw.h, but other than\nthat, it seems we rely on these being available. There's some discussion\nin ebc3278665 (\"git-compat-util.h: drop the `PRIuMAX` and other fallback\ndefinitions\", 2019-11-24).\n\nMartin\n"},{"id":"391275","messageId":"xmqqk14ze806.fsf@gitster-ct.c.googlers.com","threadId":"52754","inReplyTo":"CAN0heSqoU1NxOtwaE_ZBBzghLXAeC4CxVh1x8R-efOVtbHdA5g@mail.gmail.com","subject":"Re: Printing a uint64_t portably in Git?","fromName":"Junio C Hamano","fromEmail":"gitster@pobox.com","sentAt":"2020-02-06T21:11:21Z","receivedAt":"2020-02-06T21:11:26Z","isPatch":false,"sender":{"key":"gitster@pobox.com","avatar":"https://avatars.githubusercontent.com/u/54884?v=4"},"body":"Martin Ågren writes:\n\n> On Thu, 6 Feb 2020 at 18:54, Han-Wen Nienhuys wrote:\n>> What is the right incantation to do printf of a uint64_t on OSX ?\n>>\n>> Apparently PRIuMAX is to be used for \"uintmax_t\", and not for \"long\n>> long unsigned int\".\n>\n> You could cast it?
