+Summary: gmcs does not emit generic parameter constraints on structs
+
+Looks like gmcs or SRE does not emit generic parameter constraints. Here is
+an example (which also contains test for bug #82064), ran on cygwin (note
+that #82064 is for runtime).
+
+$ cat get-arg.cs
+using System;
+using System.Collections.Generic;
+using System.Reflection;
+
+public struct Foo<T> where T : struct
+{
+}
+
+public class Test
+{
+        public static void Main ()
+        {
+                DoTest (typeof (Foo<int>));
+                DoTest (typeof (int?));
+        }
+
+        static void DoTest (Type type)
+        {
+                Type t = type.GetGenericTypeDefinition ();
+                Type n = t.GetGenericArguments () [0];
+                Console.WriteLine ("{0} {1} {2}",
+                        t, n, n.GetGenericParameterConstraints ().Length);
+        }
+}
