System: Linux churchill 2.4.3-12 #1 Fri Jun 8 15:05:56 EDT 2001 i686 unknown
Architecture: i686

>Description:
	If a class A defines an inner class AA, and B extends A, then
        references to B.AA fail.
>How-To-Repeat:
	A.java:

        public class A {
            public static class AA { }
        }

        B.java:

        public class B extends A {
        }

        C.java:

        public class C {
            B.AA f() {
                return null;
            }
        }

        gcj -v C.java:

        Class path starts here:

        C.java:2: error: Type `B.AA' not found in the declaration of the return type of method `f'.
               B.AA f() {
               ^
        1 error

        This works with javac.
>Fix:
	A workaround is to mark C.f as returning A.AA instead of B.AA.
