Also, for it to become an extended integer type, it would be necessary to=20
define integer constant suffixes and implement printf / scanf support in=20
the library, because <stdint.h> is now required to provide intN_t /=20
uintN_t when there is a matching standard or extended integer type, so=20
would be required to provide int128_t / uint128_t, which in turn would=20
require the corresponding <stdint.h> and <inttypes.h> macros, so requiring=
=20
constant suffixes and printf / scanf support.=
