{noformat}
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.
