* 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 accommodate 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 accommodate these targets, a required minimum-width type is only
* defined if there exists an exact-width type of equal or greater width.
