Default Bug#660698: gnat-4.6: Legal program rejected. Use in subpackage invalidates use type

Package: gnat-4.6
Version: 4.6.2-3
Severity: normal

I reported the problem to
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52319).

The following legal program is rejected by "gnatgcc -c proc.adb" with

proc.adb:17:28: there is no applicable operator "And" for type
"Standard.Integer"

All works fine if P2 is removed.

procedure Proc is
package P1 is
type T is new Integer;
function "and" (L, R : in Integer) return T;
end P1;
package body P1 is
function "and" (L, R : in Integer) return T is
pragma Unreferenced (L, R);
begin
return 0;
end "and";
end P1;
use type P1.T;
package P2 is
use P1;
end P2;
G : P1.T := Integer'(1) and Integer'(2);
begin
null;
end Proc;
