Or rather
/* Allow conversions pointer type to integral type only if
there is no sign or zero extension involved.
For targets were the precision of ptrofftype doesn't match that
of pointers we need to allow arbitrary conversions to ptrofftype.
*/
if (POINTER_TYPE_P (rhs1_type)
&& INTEGRAL_TYPE_P (lhs_type)
&& (TYPE_PRECISION (rhs1_type) >= TYPE_PRECISION (lhs_type)
|| ptrofftype_p (sizetype)))
return false;
as restricting conversion from integral to pointers does not seem necessary
(only pointers do not have a "sign").
