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