+Summary: mcs has problems with const enums and casts
+
+Description of Problem: 
+ 
+In a constant initialization expression, mcs flags an error when the  
+expression involves a cast from an integer that does not correspond to an 
+ordinal value of the enum: 
+ 
+using System; 
+ 
+ 
+public class Testing 
+{ 
+    public enum INT : int { Zero } 
+    public const INT JPEG_SUSPENDED = (INT)0; 
+    public const INT JPEG_HEADER_OK = (INT)1; 
+    public const INT JPEG_HEADER_TABLES_ONLY = (INT)2; 
+ 
+    public static void Main() 
+    { 
+ 
+    } 
+} 
+ 
+ 
+Steps to reproduce the problem: 
+1. mcs whatever.cs 
+ 
+ 
+Actual Results: 
+ 
+agc.cs(8) error CS0150: A constant value is expected 
+agc.cs(9) error CS0150: A constant value is expected 
+ 
+ 
+ 
+Expected Results: 
+ 
+Successful compilation 
+
