it's purely a compiler issue. Besides, do we start repeating the GCC manual too, while we're at it? At some point we need to restrain ourselves and stay within the scope of the man pages. PS. Have you ever tried to use __int128 in real code? I have, to my regret. It's a portability and bug minefield and should not be used unless you really know what you're doing, which most people do not.
