How are the PRI* macros better than an intmax_t cast? In my opinion, the intmax_t cast and %j is the best, realistic solution for this. I have partitioned in the past that we change int64 types to "long long" on platforms with 64bit "long". That way you can print int64 types with "%ll" on all platforms. But casting to intmax is just as good and the compiler should be able to figure out what goes on and make it a no-op. Regards, Max
