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