[IronPython] problem compiling extension methods on IPy2b5

[Curt Hagenlocher]

Ouch.
For now, you can work around this problem by adding an ExtensionAttribute
class to your own source.  The code would look like this:

using System;
namespace System.Runtime.CompilerServices {
    [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class |
AttributeTargets.Assembly)]
    sealed class ExtensionAttribute : Attribute { }
}
