//  This is not a complete implementation of the 1999 C Standard stdint.h
//  header; it doesn't supply various macros which are not advisable for use in
//  C++ programs.

#include <limits.h> // implementation artifact; not part of interface

//  These are fairly safe guesses for some 16-bit, and most 32-bit and 64-bit
//  platforms.  For other systems, they will have to be hand tailored.
//  Because the fast types are assumed to be the same as the undecorated types,
//  it may be possible to hand tailor a more efficient implementation.
