+Summary: MCS does not report error when the same attribute is assigned twice
+
+mcs does not report error CS0579 when an Attribute with AllowMultiple set 
+to false is assigned to a member more than once.
+
+using System;
+
+[assembly:CLSCompliant(true)]
+
+namespace DuplicateAttributes {
+	[CLSCompliant(true)]
+	[CLSCompliant(true)]
+	public class ClassA {
+		[CLSCompliant(true)]
+		[CLSCompliant(true)]
+		public ClassA() {
+		}
+
+		[CLSCompliant(true)]
+		[CLSCompliant(true)]
+		public void Method() {
+		}
+
+		[CLSCompliant(true)]
+		[CLSCompliant(true)]
+		public string Test {
+			get { return ""; }
+		}
+	}
+}
+
+This results in the following errors on csc :
+
+test.cs(7,3): error CS0579: Duplicate 'CLSCompliant' attribute
+test.cs(10,4): error CS0579: Duplicate 'CLSCompliant' attribute
+test.cs(15,4): error CS0579: Duplicate 'CLSCompliant' attribute
+test.cs(20,4): error CS0579: Duplicate 'CLSCompliant' attribute
+
+while mcs does not report any error at all.
