+Summary: Type lookup problem in delegate declaration
+Description of Problem:
+The type lookup uses Delegate.Parent as the TypeContainer (Delegate is 
+not a TypeContainer like class and structs are) but this removes a full 
+level of possible targets for the type search.
+More detailed information:
+By looking for the type in the Parent, the search for the type does not 
+try to get 'N1'+'A' where 'A' is the type we are looking for and 'N1' is 
+the namespace where the delegate is declared.
+This type lookup problem is similar to bug_21092 where the same one level 
+jump is done. The difference is that 'Interface' is a 'DeclSpace' and 
+this allows for a RootContext.LookupType but in the Delegate i can't find 
+information that lead the type search to the correct type.
+Additional Information:
+Using snapshot of Feb-26-02
+Source code to reproduce the problem:
+namespace N1
+	public class A
+	{		
+	}
+	public delegate void B(object sender, N1.A a);//<- works
+	public delegate void C(object sender, A a);//<-fails
