[Bug ada/17320] New: Illegal program not detected, name hidden by use clauses, RM 3.9.3(11)

["ludovic dot brenta at insalien dot org" <gcc-bugzilla at gcc dot gnu dot org>]

(Debian bug #269948)

--  RM 3.9.3/11 A generic actual subprogram shall not be an abstract
--  subprogram.  works OK if unrelated line (A) is commented out.
package Test_269948 is
   generic
      with function "=" (X, Y : integer) return Boolean is <>;   --(A)
   package pak1 is
      function "=" (X, Y: float) return Boolean is abstract;
      generic
         with function Equal (X, Y : float) return Boolean is "=";  --ERROR:
      package pak2 is
      end pak2;
   end pak1;

   package new_pak1 is new pak1;
   package new_pak2 is new new_pak1.pak2;
end Test_269948;



The above program compiles without an error with GNAT 3.15p and GCC
3.4.  The compiler should instead print something like:

test_269948.ads:15:04: abstract subprogram not allowed as generic actual
gnatmake: "test_119.ads" compilation error
