I understand that your Gen_Linked_List generic package declares the
generic type Gen_Linked_List.List formal parameter as being limited
private. In that case, you can't use it as a record component type
(assignment issues). The only workaround is to use an access to this
type. Like this:

    type List_Access_Type is access MyList.List;
    type Hggra is
        record
            Id              : Integer;
            Int_List_Access : List_Access_Type;
        end record;

Of course, you'll have a manage your self allocations and deallocations
of objects of type List_Access_Type.
