+Summary: unfixable warning cs0067 "event not used"
+
+If an interface defines an event, and an implementation of that
+interface never invokes the event, mcs complains:
+
+	using System;
+	
+	public interface IFoo {
+		event EventHandler blah;
+	}
+	
+	public class Foo : IFoo {
+		public static void Main ()
+		{
+			;
+		}
+	
+		public event EventHandler blah;
+	}
+
+	danw@twelve-monkeys:tmp> mcs -o ev.exe ev.cs
+	ev.cs(13) warning CS0067: The event 'Foo.blah' is never used
+
+but if you don't define it, you get an error for not fully
+implementing the interface.
+
+The warning is consistent with csc, but it seems wrong.
