>Description:
gcj rejects legal code of anonymous inner classes with the following error message

roland@isabella:~/work> gcj -C Test.java
IntProcedure.java: In class `Test$1':
IntProcedure.java: In constructor `(Test,int)':
IntProcedure.java:22: Local variable `parm$key' can't be accessed from within the inner class `Test$1' unless it is declared final.
   <<file too short - unexpected EOF>>
   ^
IntProcedure.java:1: internal error in generate_bytecode_insn - tree code not implemented: error_mark

>How-To-Repeat:
	

public interface IntProcedure {
    public int apply();
}
import IntProcedure;

public class Test {

    public Object a(final int key) {
	return new IntProcedure() {
			public int apply() {
			    return key;
			}
		};
    }

    public Object  b(final int value) {
	return new IntProcedure() {
			public int apply() {
			    return value;
			}
		};
    }
