563 Specifically, perl internals don't support long long. Among
564 the many problems is that some compilers support long long,
565 but the underlying library functions (such as sprintf) don't.
566 Some things do work (such as quad pack/unpack on convex);
567 also some systems use long long for the fpos_t typedef. That
568 seems to work too.
569
570 The IV type is supposed to be long enough to hold any integral
571 value or a pointer.
