/*
 * MSVC++ doesn't include <inttypes.h>, even in versions shipping <stdint.h>, so
 * we have to reimplement it there.  Note: <inttypes.h> #includes <stdint.h>.
 *
 * Note that this header DOES NOT implement <inttypes.h>'s scanf macros.  MSVC's
 * scanf doesn't have sufficient format specifier support to implement them
 * (specifically, to implement scanning into an 8-bit location).
 *
 * http://stackoverflow.com/questions/3036396/scanfd-char-char-as-int-format-string
 *
 * Moreover, scanf is a footgun: if the input number exceeds the bounds of the
 * target type, behavior is undefined (in the compiler sense: that is, this code
 * could overwrite your hard drive with zeroes):
 *
 *   uint8_t u;
 *   sscanf("256", "%" SCNu8, &u); // BAD
 *
 * This header will sometimes provide SCN* macros, by dint of being implemented
 * using <inttypes.h>.  But for these reasons, *never* use them!
