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