+Summary: [GMCS] gmcs incorrect chooses non-generic GetEnumerator () method
+
+Test case:
+<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
+using System;
+using System.Threading;
+using System.Collections;
+using System.Collections.Generic;
+
+public class Dict : Dictionary <object, object>
+{
+}
+
+public class Foo
+{
+	public static void Main () {
+		IDictionary<object, object> dict = new Dict ();
+
+		dict.Add (new Object (), new Object ());
+		foreach (object kv in dict)
+			Console.WriteLine (kv.GetType ());
+	}
+}
+<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
+
+When compiling this with gmcs, it prints:
+System.Collections.DictionaryEntry
+
+When compiling it with csc, it prints:
+System.Collections.Generic.KeyValuePair`2 
+
+This is because gmcs generates a call to :
+
+ callvirt instance class[mscorlib]System.Collections.IEnumerator class
+[mscorlib]System.Collections.IEnumerable::GetEnumerator()
+
+while csc generates a call to the generic GetEnumerator () method.
