>Description:
The following code fails to compile because gcj is looking in the wrong Foo class for the constructor:

| public class Test {
|     public void func1() {
| 	class Foo {
| 	    Foo(int i) {
| 	    }
| 	}
| 	Foo f = new Foo(1);
|     }
|     public void func2() {
| 	class Foo {
| 	    Foo(boolean b) {
| 	    }
| 	}
|     }
| }

The error message given is as follows:

| Test.java: In class `Test':
| Test.java: In method `Test.func1()':
| Test.java:7: Can't find constructor `Test$2$Foo(I)' in type `Test$2$Foo'.
|         Foo f = new Foo(1);
|                        ^
| 1 error

 I looked at this last night.
 
 It turns out that gcj has no notion of scope for member classes.  It
 puts them all in a single list attached to the class.  So the problem
 is that basic required functionality is missing from gcj.
