linux i686, glibc 2.2.4, kernel 2.4.10	
>Description:
gcj doesn't compile classes when they have a 
static inner class And call the class without explicit
use of the fqn
Suppose : 
class A
{
  static class inner
  {}
}

If another class like (ex: B) imports 
A.inner, 
it must call inner A.inner to refer to the inner class 
to be commpiled, but with java, this is not compulsory,
once you imported A.inner, inner suffishes to refer to the inner class.

 Nic Ferrier sent this test case.
 
 file a.java:
 
 public class A
 {
    public static X createSomething ()
    {
      return new X();
    }
 
    public class X
    {
       public void someMethod ()
       {
         return;
       }
    }
 }
 
 
 file b.java:
 
 import A.X;
 
 public class B
 {
    public void someThing ()
    {
      X var = A.createSomething();
      var.someMethod();
    }
 }
 
 
 But trying to compile this with GCJ produces the following error:
 
 
 ./../paperclips/source/gnu/paperclips/WebApp.java:173: 
 Type `X' not found in the declaration of the local variable `var'.
         X var = (X) A.createSomething();
 
 
 This does compile with javac.
 
 If GCJ does this it won't be able to compile javamail which also uses
 import references to inner classes.
