+ Specifically, perl internals don't support long long. Among
+ the many problems is that some compilers support long long,
+ but the underlying library functions (such as sprintf) don't.
+ 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
