/* cross-platform printf() format specifiers:
 *
 * Note: MS apparently does recognize "ll" as "l" in its printf() routines, but "I64" is
 * preferred for 64-bit types.  _MSC_VER and _WIN32 are always defined for Visual Studio
 * builds. To check if the build is using 64-bit Visual Studio, you must check if the
 * _WIN64 macro is defined.
 *
 * MinGW note: __MINGW64__ and __MINGW32__ are both defined by 64-bit gcc. Check
 * for __MINGW64__ before __MINGW32__.
 *
 *
 * LL_FMT: long long format modifier, e.g. "%016" LL_FMT "x"
 * SIZE_T: size_t format modifier, e.g., "%" SIZE_T_FMT "u" (can use "d", but you will
 *         probably get a warning.)
 * T_UINT64_FMT: t_uint64 format modifier, e.g. "%016" T_UINT64_FMT "x"
 * T_INT64_FMT: t_int64 format modifier, e.g., "%" T_INT64_FMT "d"
 * POINTER_FMT: Format modifier for pointers, e.g. "%08" POINTER_FMT "X"
