This is strictly a libc question rather than a purely compiler question.
Old BSDs spelled %lld %qd (q = quad) though modern ones have supported
%lld since it became the wider standard. I think I'd be surprised if there
are systems without long long and %lld any more.

The C99 solution is to cast to intmax_t (the largest integer type which
may be wider than long long) and use the corresponding %jd format
specifier. But only a few systems support this at the moment.
