68  *
69  * The standard requires that exact-width type be defined for 8-, 16-, 32-, and
70  * 64-bit types if they are implemented. Other exact width types are optional.
71  * This implementation defines an exact-width types for every integer width
72  * that is represented in the standard integer types.
73  *
74  * The standard also requires minimum-width types be defined for 8-, 16-, 32-,
75  * and 64-bit widths regardless of whether there are corresponding exact-width
76  * types.
77  *
78  * To accommodate targets that are missing types that are exactly 8, 16, 32, or
79  * 64 bits wide, this implementation takes an approach of cascading
80  * redefinitions, redefining __int_leastN_t to successively smaller exact-width
81  * types. It is therefore important that the types are defined in order of
82  * descending widths.
83  *
84  * We currently assume that the minimum-width types and the fastest
85  * minimum-width types are the same. This is allowed by the standard, but is
86  * suboptimal.
87  *
88  * In violation of the standard, some targets do not implement a type that is
89  * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
90  * To accommodate these targets, a required minimum-width type is only
91  * defined if there exists an exact-width type of equal or greater width.

482  *
483  * The presence of limit macros are completely optional in C99.  This
484  * implementation defines limits for all of the types (exact- and
485  * minimum-width) that it defines above, using the limits of the minimum-width
486  * type for any types that do not have exact-width representations.
487  *
488  * As in the type definitions, this section takes an approach of
489  * successive-shrinking to determine which limits to use for the standard (8,
490  * 16, 32, 64) bit widths when they don't have exact representations. It is
491  * therefore important that the definitions be kept in order of decending
492  * widths.
493  *
494  * Note that C++ should not check __STDC_LIMIT_MACROS here, contrary to the
495  * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).
