These macros are defined to the correct underlying types for the
-@code{size_t}, @code{ptrdiff_t}, @code{wchar_t}, and @code{wint_t}
+@code{size_t}, @code{ptrdiff_t}, @code{wchar_t}, @code{wint_t},
+@code{intmax_t}, and @code{uintmax_t}
typedefs, respectively. They exist to make the standard header files
@file{stddef.h} and @file{wchar.h} work correctly. You should not use
these macros directly; instead, include the appropriate headers and use

Defined to the maximum value of the @code{signed char}, @code{wchar_t},

+@code{signed int}, @code{signed long}, @code{signed long long}, and
+@code{intmax_t} types
respectively. They exist to make the standard header given numerical limits
work correctly. You should not use these macros directly; instead, include
the appropriate headers.
