Aha, I see you didn't follow the lengthy discussion about "long long".
WG14 deliberately broke ISO C 90 by adopting "long long" -- ISO C90
said "long" is the widest integer type.
(The French national body, for a long time disapproved "long long"
preceisely for that breakage.)  But that is another story since the
standard was approved.

I'd much prefer it be activated on demand.
