Specifically, perl internals don't support long long. Among
the many problems is that some compilers support long long,

Some things do work (such as quad pack/unpack on convex);
also some systems use long long for the fpos_t typedef. That
seems to work too.
The IV type is supposed to be long enough to hold any integral
