gcc-4.4.3-4.fc12.x86_64

No, moving that code doesn't fix it.  Still very mysterious.  The claim is 
that
template <typename ExceptionType = broken_constraint>
struct throw_exception

in constrained.hpp conflicts with 

template<class E> BOOST_ATTRIBUTE_NORETURN inline void throw_exception( E 
const & e )

in throw_exception.hpp

in call to 'throw_exception' in the code we just moved, but the 
throw_exception in constrained.hpp is in
namespace boost {
/// The Boost Constrained Value library's namespace.
namespace constrained_value {

namespace, so I don't see how it conflicts.

If someone wants to try it, I put the 2 files here:
