An unsigned integer type
|

capable of representing any value of any unsigned integer type
|

supported by the implementation.

According to the C language standard, it shall be

capable of storing values in the range [0,

The macro

Bugs:
|

.I uintmax_t
|

is not large enough to represent values of type
|

.I unsigned __int128
|

in implementations where
|

.I unsigned __int128
|

is defined and

.I unsigned long long
|

is less than 128 bits wide.
