659 Specifically, perl internals don't support long long. Among
660 the many problems is that some compilers support long long,
661 but the underlying library functions (such as sprintf) don't.
662 Some things do work (such as quad pack/unpack on convex);
663 also some systems use long long for the fpos_t typedef. That
664 seems to work too.
665
666 The IV type is supposed to be long enough to hold any integral
