70 * C99 7.18.1.2 Minimum-width integer types.
71 * C99 7.18.1.3 Fastest minimum-width integer types.
72 *
73 * The standard requires that exact-width type be defined for 8-, 16-, 32-, and
74 * 64-bit types if they are implemented. Other exact width types are optional.
75 * This implementation defines an exact-width types for every integer width
76 * that is represented in the standard integer types.
77 *
78 * The standard also requires minimum-width types be defined for 8-, 16-, 32-,
79 * and 64-bit widths regardless of whether there are corresponding exact-width
80 * types.
81 *
82 * To accommodate targets that are missing types that are exactly 8, 16, 32, or
83 * 64 bits wide, this implementation takes an approach of cascading
84 * redefinitions, redefining __int_leastN_t to successively smaller exact-width
85 * types. It is therefore important that the types are defined in order of
86 * descending widths.
87 *
88 * We currently assume that the minimum-width types and the fastest
89 * minimum-width types are the same. This is allowed by the standard, but is
90 * suboptimal.
91 *
92 * In violation of the standard, some targets do not implement a type that is
93 * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
94 * To accommodate these targets, a required minimum-width type is only
95 * defined if there exists an exact-width type of equal or greater width.

315 * types are required, the corresponding integer constant macros are defined

318 * defined below, too.
319 *
320 * These macros are defined using the same successive-shrinking approach as
321 * the type definitions above. It is likewise important that macros are defined
322 * in order of decending width.
323 *
324 * Note that C++ should not check __STDC_CONSTANT_MACROS here, contrary to the
325 * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).

483/* C99 7.18.2.1 Limits of exact-width integer types.
484 * C99 7.18.2.2 Limits of minimum-width integer types.
485 * C99 7.18.2.3 Limits of fastest minimum-width integer types.
486 *
487 * The presence of limit macros are completely optional in C99. This
488 * implementation defines limits for all of the types (exact- and
489 * minimum-width) that it defines above, using the limits of the minimum-width
490 * type for any types that do not have exact-width representations.
491 *
492 * As in the type definitions, this section takes an approach of
493 * successive-shrinking to determine which limits to use for the standard (8,
494 * 16, 32, 64) bit widths when they don't have exact representations. It is
495 * therefore important that the definitions be kept in order of decending
496 * widths.
497 *
498 * Note that C++ should not check __STDC_LIMIT_MACROS here, contrary to the
499 * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).
