>Description:
javac and jikes generate a synthetic constructor for the example given:

5: invokespecial #3=<Method Outer$Inner.<init> (Outer$1)void>

gcj however attempts to access the constructor declared private, failing at runtime with an IllegalAccessError:

4: invokespecial #13=<Method Outer$Inner.<init> ()void>

Also gcj doesn't generate the synthetic Outer$Inner constructor at all.
>How-To-Repeat:
$ cat Outer.java
public class Outer {
	public Object getInner() {
		return new Inner();
	}
	private static class Inner {
		private Inner() {
		}
		public String toString() {
			return "OK";
		}
	}
	public static void main(String[] args) {
		Outer outer = new Outer();
		System.out.println(outer.getInner());
	}
}
$ gcj -C Outer.java
$ gij Outer
