The above sounds reasonable, if there aren't too many different such
function prototypes.

On the other hand, if you insist on the flexibility of the
unchecked-conversion method, then it might make more sense to
unchecked-convert from one access-to-subp type to another (both types
being pragma Convention(C)).  This is more likely to be portable in
practise than unchecked-converting from type System.Address to
access-to-subp.  No guarantees, of course.
