New description:

 {{{
 -----
 #include <boost\optional.hpp>

 #using <mscorlib.dll>
 #include <tchar.h>

 using namespace System;

 enum Numbers { Zero, One, Two, Three };

 // This is the entry point for this application
 int _tmain(void)
 {
         boost::optional<Numbers> num;

     return 0;
 }
 -----

 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,
