 interface never invokes the event, mcs complains:

 Marek, do you think you could look at this?

+I don't think this is an issue.
+
+In both cases (abstract base class or interface defining
+an event) the warning can be avoided using empty "add" and
+"remove" accessors:
+
+	public class Foo : IFoo {
+		...
+		public event EventHandler blah {
+			add {}
+			remove {}
+		}
+	}
+
+The warning is even useful: it reminds you that you *should*
+use add {} and remove {} to avoid the generation of the
+unnecessary hidden delegate.
