Considering this is the C standard, the result will be as vague as
possible. The best wording would be something like "hey, it's no less than
long long, and might bigger, but this is implementation-defined, here are
another 10 macros you need to check". Given that long long is 64-bit, I'd
assume long long long would be 128-bit, and long long long long would be
256-bit... You get the idea what happens next. :-)
BTW, folks from Plan 9 were so tired of this crap they have typedef long
long vlong. I guess "v" stands for "very". I have no idea how they would
call long long long. :-)
