+Summary: [GMCS] incorrect compilation of foreach
+
+Given the following test:
+using System;
+using System.Collections;
+using System.Collections.Generic;
+
+class MyEnum : IEnumerator {
+       int count = 0;
+       public object Current {
+               get {return "";}
+       }
+       public bool MoveNext () {
+               if (count > 0)
+                       return false;
+               count++;
+               return true;
+       }
+       public void Reset () {
+       }
+}
+class MyDict : IEnumerable<KeyValuePair<object,object>> {
+       IEnumerator<KeyValuePair<object, object>> 
IEnumerable<KeyValuePair<object,
+object>>.GetEnumerator() {
+               KeyValuePair<object, object> o = new KeyValuePair<object, 
object>
+("hello", "world");
+               yield return o;
+       }
+       public IEnumerator GetEnumerator() {
+               return new MyEnum ();
+       }
+}
+class T {
+       static void Main () {
+               MyDict dict = new MyDict ();
+               foreach (KeyValuePair<object, object> o in dict) {
+                       Console.WriteLine ("{0} {1}", o.Key, o.Value);
+               }
+       }
+}
+
+Compiling with gmcs yields a cast exception. This is because gmcs
+calls the non-generic GetEnumerator() instead of the proper generic
+implementation that returns KeyValuePair<object, object values.
+This is a reduced test case from ironpython code. This bug makes a
+gmcs-compiled ironpython (1.1) unusable.
