704/* XXX QUAD stuff is not currently supported on most systems.
705 Specifically, perl internals don't support long long. Among
706 the many problems is that some compilers support long long,
707 but the underlying library functions (such as sprintf) don't.
708 Some things do work (such as quad pack/unpack on convex);
709 also some systems use long long for the fpos_t typedef. That
710 seems to work too.
711
712 The IV type is supposed to be long enough to hold any integral
713 value or a pointer.
