+Summary: CS0229 / CS0122 errors reported when hiding property in interface
+
+When a given property from an interface B hides a property from an 
+implemented interface A, then mcs reports errors CS0229 and CS0122 when 
+another interface (C) implements B.
+
+To reproduce, compile the following code fragment:
+
+public class Test
+{
+  private C _vssItem = null;
+
+  public string Spec {
+    get { return _vssItem.Spec; }
+  }
+
+  public void Checkout ()
+  {
+    _vssItem.Checkout ();
+  }
+}
+
+interface A
+{
+  void Checkout ();
+  string Spec
+  {
+    get;
+  }
+}
+
+interface B : A
+{
+  new void Checkout ();
+  new string Spec
+  {
+    get;
+  }
+}
+
+interface C : B
+{
+}
+
+Expected result:
+
+Successful compilation.
+
+Actual result:
+
+test.cs(6,16): error CS0229: Ambiguity between `B.Spec' and `A.Spec'
+test.cs(27,13): (Location of the symbol related to previous error)
+test.cs(18,9): (Location of the symbol related to previous error)
+test.cs(6,16): error CS0122: `A.Spec' is inaccessible due to its 
+protection level
+test.cs(18,9): (Location of the symbol related to previous error)
