/* As the minimum-width types - for the required widths of 8, 16, 32, and 64
   bits - are expressed in terms of the exact-width types, the mechanism for
   these macros is to append the literal of that exact-width type to the macro

   This is considered a hack, as the author is not sure his understanding of
   the requirements of this macro is correct. Any input appreciated.
