655 Specifically, perl internals don't support long long. Among
656 the many problems is that some compilers support long long,
657 but the underlying library functions (such as sprintf) don't.
658 Some things do work (such as quad pack/unpack on convex);
659 also some systems use long long for the fpos_t typedef. That
660 seems to work too.
