GCC 4.0.0

Compiling the following two classes produces error:
p2/B.java:7: error: Method ‘p1.A.f(int)’ was defined with return type
‘boolean’in class ‘p1.A’.
      void f( int x ) {}

/// A.java ///

package p1;
public class A
{
   boolean f( int x ) { return false; }
}

/// B.java ///

package p2;
import p1.A;

public class B extends A
{
   void f( int x ) {}
}

//////////////////

To reproduce place A.java in a directory p1, and B.java in directory p2.
Then compile B.java: gcj -C p2/B.java

A.f(...) should not be visible to class B and hence not cause this compilation
error. Sun's javac compiles these classes without error.
