643 Specifically, perl internals don't support long long. Among
644 the many problems is that some compilers support long long,
645 but the underlying library functions (such as sprintf) don't.
646 Some things do work (such as quad pack/unpack on convex);
647 also some systems use long long for the fpos_t typedef. That
648 seems to work too.
649
650 The IV type is supposed to be long enough to hold any integral
651 value or a pointer.
