/* C99 7.18.1.1 Exact-width integer types.
 * C99 7.18.1.2 Minimum-width integer types.
 * C99 7.18.1.3 Fastest minimum-width integer types.
 *
 * The standard requires that exact-width type be defined for 8-, 16-, 32-, and
 * 64-bit types if they are implemented. Other exact width types are optional.
 * This implementation defines an exact-width types for every integer width
 * that is represented in the standard integer types.
 *
 * The standard also requires minimum-width types be defined for 8-, 16-, 32-,
 * and 64-bit widths regardless of whether there are corresponding exact-width
 * types.
 *
 * To accomodate targets that are missing types that are exactly 8, 16, 32, or
 * 64 bits wide, this implementation takes an approach of cascading
 * redefintions, redefining __int_leastN_t to successively smaller exact-width
 * types. It is therefore important that the types are defined in order of
 * descending widths.
 *
 * We currently assume that the minimum-width types and the fastest
 * minimum-width types are the same. This is allowed by the standard, but is
 * suboptimal.
 *
 * In violation of the standard, some targets do not implement a type that is
 * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
 * To accomodate these targets, a required minimum-width type is only
 * defined if there exists an exact-width type of equal or greater width.
