+Summary: [PATCH] IsDefined() is mis implemented.
+IsDefined() is mis implemented.
+In MonoCustomAttrs.cs:
+			MethodInfo baseMethod = method.GetBaseDefinition ();
+GetBaseDefinition() not return its direct super method, but the virtual
+method where its first declared. And there is no standrad way do this. I
+hacked it:
++			return t.GetMethod(method.Name, BindingFlags.FlattenHierarchy |
+BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.NonPublic
+| BindingFlags.Public, null, GetMethodParameterTypes(method), null);
+			BindingFlags.FlattenHierarchy will search Method up and find the first
+virtual method.
+There is another problem, Attribute itself can determinate whether inheriting. 
++			if (inherit && GetUsage(attributeType).Inherited && ((btype = GetBase
+(obj)) != null))
+Maybe GetCustomAttributes also contains such problems.
