Could someone please explain
  "subprogram must not be deeper than access type".

I want package utilities to offer
  type p is access procedure(x:in integer);
and
  procedure do_stuff(how : in p);

But if my main program 'with utilities' and
  procedure this_is_how(x:in integer);
..
  utilities.do_stuff(this_is_how'access);

I get that message from GNAT 3.04 for DOS.  I also note the same problem
prevents compilation of the PMV16 OS/2 bindings, and is gotten around
in the new OS/2 bindings with "this_is_how'unrestricted_access", which
I don't see in the LRM.  The message indicates an understandable
problem, but what's the workaround to allow my package utilities to
offer a do_stuff procedure.
