   Easy:

package ADT is 
   type Froz is new Integer;
   procedure Mumble(F: in out Froz);
end ADT;

package body ADT is
   procedure Mumble(F: in out Froz) is
   begin F := F + 1; end Mumble;
end ADT;

with ADT;
procedure Main is
   type Frozbaz is new ADT.Froz;
   X: Frozbaz := 0;
begin
   Mumble(X);
end Main;
