 /* Implements the C99 <inttypes.h> interface, minus the SCN* format macros. */

 /*

  * 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!
