gcc version 2.96 20000525 (experimental)
>Description:
A "protected" field in anything other than "this" should 
not be accessible to a class outside the current instance,
if it is declared in another package (even if the current
class is a subclass of the declaring class)

gcj incorrectly permits the following code:

// file: pkg1/A.java
package pkg1;
public class A 
{
  protected int i;
}

// file: pkg2/B.java
package pkg2;
public class B extends pkg1.A 
{
  public B(pkg1.A a)
  {
    int i = a.i;
  }  
}

Note that this code is still incorrectly accepted even if 
the "extends pkg1.A" is removed.
