+Summary: mcs does not respect explicit casting of null
+
+mcs reject to compile explicit cast of null to a certain type.
+
+using System;
+public class Test
+{
+        public static void Main ()

+                bool ret = (DBNull) null == null;
+        }
+}
+
+Actual Results:
+
+const-null.cs(6,15): error CS0031: Constant value `System.DBNull' cannot be
+converted to a `int'
+const-null.cs(6,15): error CS0037: Cannot convert null to `int' because it
+is a value type
+
+Expected Results:
+
+no error.
+
+How often does this happen? 
+
+consistently.
