+Summary: MCS incorrectly reports "Class definition is circular" when it's unable to find a type
+
+When you have a class which either derives from a class or implements an interface which does not exist, you get a (correct) error message 
+that this class / interface does not exist, but also a lot of error messages that the classes definition is circular.
+
+=====
+using System;
+
+class X : Y
+{
+	public long Foo;
+}
+
+class Z : X
+{
+	public int Bar;
+}
+
+class Test
+{
+	static void Main ()
+	{ }
+}
+=====
+
+When compiling this example, you get:
+
+-----
+N.cs(3) error CS0246: Cannot find type `Y'
+N.cs(8) error CS0146: Class definition is circular: `X'
+N.cs(8) error CS0246: Cannot find type `X'
+-----
+
+The two CS0246's are correct, the CS0146 is not.
