I just compiled gcc for fedora, and I'm getting this error:

[Leo@chessman ~]$ cat HelloWorld.java
public class HelloWorld {
        public static void main(String[] args){
                System.out.println("Hello world!");
        }
}

[Leo@chessman ~]$ gcj -v -save-temps -o HelloWorld HelloWorld.java

I built this GCC today with the GCC I built yesterday (also 4.6.0). That also
had this java error.
