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