           Summary: EnumConstant.GetTypedValue fails due to weird way
                    Reflection.Emit works with enums
           Product: Mono: Compilers
           Version: 1.9.0
          Platform: x86
        OS/Version: Windows XP

System.Enum.ToObject cannot process TypeBuilders, i.e the case when enum is
created via Reflection.Emit and not existing 'real' enum.

There is a basic workaround in code, but it doesn't work properly under
original .NET 2.0 SP1.

Mono.CSharp.EnumConstant.GetTypedValue
Seems to be a 'by design' problem with original Microsoft .NET 2.0 SP1
Force the workaround to be applied for all enum TypeBuilders as well.
Proposed change in ecore.cs ~1615ln
        public override object GetTypedValue()
        {
            // FIXME: runtime is not ready to work with just emited enums
            if (!RootContext.StdLib 
#if MS_COMPATIBLE
                || type is TypeBuilder
#endif
                )
            {
                return Child.GetValue();
            }

            return System.Enum.ToObject(type, Child.GetValue());
        }
