Which might or might not be int64_t. Given that int128_t is already on the horizon (newer gcc already support __int128 on 64bit machines...), I wouldn't be surprised if intmax_t is growing to 128bit eventually. Format strings don't really have a nice way to print fixed-size integers I fear... the only stuff that is correct is the "PRIu64" macro, but that's fricking ugly... I think PRIu64 is still a better, more future-proof option than %j though...
