708 Specifically, perl internals don't support long long. Among
709 the many problems is that some compilers support long long,
710 but the underlying library functions (such as sprintf) don't.
711 Some things do work (such as quad pack/unpack on convex);
712 also some systems use long long for the fpos_t typedef. That
713 seems to work too.
714
