In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>. Do not include it. The use of PRI* makes the code super-ugly. You can simply use "l" for printing uintptr_t, "ll" for u64, and no modifier for u32.
