533 Specifically, perl internals don't support long long. Among
534 the many problems is that some compilers support long long,
535 but the underlying library functions (such as sprintf) don't.
536 Some things do work (such as quad pack/unpack on convex);
537 also some systems use long long for the fpos_t typedef. That
538 seems to work too.
539
540 The IV type is supposed to be long enough to hold any integral
541 value or a pointer.
