> 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.
