The problem is that you are trying to instantiate the generic inside
your main procedure -- and hence, the controlled type is not at the
library level. The error message is a bit misleading, because it is
reported for the declaration within the generic package. But that one
obviously *is* at the library level. [I think I've heard rumours that
the GNAT team wants to enhance that error message, maybe they already
did so, are you using the current version of GNAT?]
Anyway, the solution is to instantiate the generic separately, like
package My_Stack is new Reusable (...)
as a compilation unit on its own, and then "with" that unit into your
main procedure.
