boost::optional<enum> fails with /CLR

#include <boost\optional.hpp>

using namespace System;

optional.hpp(347): error C2300: 'System::Enum' : class 
does not have a destructor called '~T'

I'm using boost 1.31.0; this fails in both VC7.0 and 
VC7.1.

Removing "#using <mscorlib.dll>" and "using namespace 
System;" gets rid of the compiler error, but then you 
can't use things like System::String*

Thanks,

Unfortunately this is due to a framework bug: System::Enum does not have a destructor (is an enum) but doesn't support a pseudo-destructor call either (see 12.4.15) which is neccesary to allow the code to compile without complaining about the lack of a destructor.
