>Description:
GCJ 3.3 seems to allow a class to access the package-private
methods of a different class even though this is not
permitted by the JLS.

Here's a simple testcase:
------------------- File: foo/Bar.java --------------------
package foo;

public class Bar {
    static void snafu( ) { }
}
---------------------------- 8< ----------------------------

------------------- File: ChkAcc.java ----------------------
public class ChkAcc {
    public void checkAccess( ) { foo.Bar.snafu( ); }
}
---------------------------- 8< ----------------------------

GCJ wrongly allows ChkAcc.java to compile successfully.

Note that this works with non-static methods as well.
It also works if a class in a named package accesses
package-private methods in the anonymous "default"
package.
