> The problem is that the fixed-size integer types map to different "natural"
> integer types, depending on the target platform. Unfortunately, the PRIxxx
> macros in inttypes.h don't work here, since gcc assumes no cross compile when
> it generates the warning. The next best solution is to cast everything to
> uintmax_t and apply the {{j}} format specifier.
