>Description:
In an inner class inherits a variable ad to outer class inherits one
with the same name GCJ can't pick the right one

--------------------------- snip ----------------------------------------------
bash-2.05a$ gcj x.java y.java y1.java 
x.java: In class `x$x1':
x.java: In method `x$x1.getId()':
x.java:6: Can't make a static reference to nonstatic variable `id' in class `x$x1'.
               return new Integer(id);
                                  ^
1 error
--------------------------- snip ----------------------------------------------

Jikes/JDK resolvs this right.
 
>How-To-Repeat:
compile this 3 files, the error is in evident in file x.java

--------------------------- snip (x.java) -------------------------------------

public class x extends y
{
    private static class x1 extends y1 {
        public Integer getId() {
            return new Integer(id); // this.id works with JDK and gcj
        }
    }
    public static void main(String[] args)
    {
	x1 t = new x1();
	System.out.println(t.getId());
    }
}

--------------------------- snip (y.java) -------------------------------------

public class y
{
    protected final int id = 1;
}

--------------------------- snip (y1.java) ------------------------------------

public class y1
{
    protected final int id = 2;
}

--------------------------- snip ----------------------------------------------

>Fix:
workaround: this.id instead of just id fix it.
