type P is access Interfaces.Unsigned_32;
type P2 is access P;
A : P2;
Of course, it's not obvious WHY you want to use two levels of indirection.
Sometimes, instead of directly translating C to Ada, it's better to think
the problem through again, and see if Ada offers a better way of solving
the problem. In general, Ada has a LOT less need of pointers (access
types) than C.
