671 Specifically, perl internals don't support long long. Among
672 the many problems is that some compilers support long long,
673 but the underlying library functions (such as sprintf) don't.
674 Some things do work (such as quad pack/unpack on convex);
675 also some systems use long long for the fpos_t typedef. That
676 seems to work too.
677
678 The IV type is supposed to be long enough to hold any integral
