677 Specifically, perl internals don't support long long. Among
678 the many problems is that some compilers support long long,
679 but the underlying library functions (such as sprintf) don't.
680 Some things do work (such as quad pack/unpack on convex);
681 also some systems use long long for the fpos_t typedef. That
682 seems to work too.
683
684 The IV type is supposed to be long enough to hold any integral
