A fig leaf for calling sv_pos_u2b with IV* where it expects I32*.

Following v5.11.3-103-gb6d1426, any compiler paying attention
whines about the pointer mismatch (which on VMS breaks the
build).

Zefram reports a further patch in progress:
  Message-ID: <20100116022631.GA10264@fysh.org>

but this gets the warning out of the way so other work can proceed.
