           Summary: gmcs can't compile comparison of variable of type
                    delegate with method
           Product: Mono: Compilers
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: vargaz at gmail.com

using System;
using System.Collections.Generic;
using System.Reflection;

class Program
        delegate IEnumerable<object> ExtensionNameTransformer(MemberInfo

        private ExtensionNameTransformer _transform;

        private IEnumerable<object> DefaultNameTransform(MemberInfo member) {
                return null;

        public void foo () {
                if (_transform == DefaultNameTransform)
                        Console.WriteLine ("FOO!");

        static void Main(string[] args) {
                new Program ().foo ();

csc compiles this just fine, while gmcs fails with:
bug.cs(16,21): error CS0019: Operator `==' cannot be applied to operands of
type `Program.ExtensionNameTransformer' and `variable'
Compilation failed: 1 error(s), 0 warnings

This prevents IronPython 2.0B1 from compiling with mono.
