Why not? If it is the longest integer.

Oh well, then 'long long' should be the
longest integer and 'long' should just be
a long one.

IIRC, this defines the 'int_XX' familiy?

Why? If want the fastest and native (for
some definition of "native" anyway) integer,
I use 'int'. If it doesn't have to be as big
and space is a mild concern, I use 'short'.
If it has to be as long as possible, I use
'long'. For many things, this is good enough.

32bit machines are in wide availability since
when? Certainly not for what I'd call "decades".
More important, I'd rather take into consideration
the lessons learned from going from to 32 and
from 32bit, instead of the 32bit itself. 32bits
will be gone soon, such transition will come
again.
