Daryle,

Following on from my previous comments - I've found at least one of the
problems with VC6, and that's the function:

    template < std::size_t Bits >
    typename boost::uint_t<Bits>::fast
    reflect( typename boost::uint_t<Bits>::fast x )

VC6 doesn't support template functions with non-type template arguments (I
think there are a few commercial unix compilers that are the same BTW), it
compiler the code, but passes garbage values to the function's template
arguments, as a result reflect just doesn't work (it basically turns the
input into garbage).  I think you can fix this, and make the code more
generally portable by using something like:

template < std::size_t Bits >
struct reflector
{
   static  typename boost::uint_t<Bits>::fast
    reflect( typename boost::uint_t<Bits>::fast x );
};

and then replacing calls to reflect<N> with calls to reflector<N>::reflect.
