+Description of Problem:
+gmcs emmitting an error where I don't belive there should be one.  Older
+version (with the 1.1.8 release) did not have the problem.
+Code:
+[awaddell at AWLNX ClassLibrary2]$ more Class1.cs 
+using System;
+using System.Collections.Generic;
+using System.Text;
+
+namespace ClassLibrary2
+{
+        public class List1<T> : List<T>
+        { }
+
+        public class List2<T>
+        {
+                private List1<T> _List = new List1<T>();
+                public void AddItem(T item)
+                {
+                        _List.Add(item);
+                }
+        }
+}
+ 
+
+Steps to reproduce the problem:
+1. gmcs -target:library Class1.cs
+2. 
+3. 
+
+Actual Results (from current tree 9/1/2005):

+Class1.cs(15) error CS1503: Argument 1: Cannot convert from `T' to `T'
+Compilation failed: 2 error(s), 0 warnings
+[awaddell at AWLNX ClassLibrary2]$

+Expected Results (from 1.1.8 release):
+[awaddell at AWLNX ClassLibrary2]$ /usr/local/bin/mcs --version

+[awaddell at AWLNX ClassLibrary2]$ /usr/local/bin/gmcs --version
