648 Specifically, perl internals don't support long long. Among
649 the many problems is that some compilers support long long,
650 but the underlying library functions (such as sprintf) don't.
651 Some things do work (such as quad pack/unpack on convex);
652 also some systems use long long for the fpos_t typedef. That
653 seems to work too.
654
655 The IV type is supposed to be long enough to hold any integral
