No, unless I also define BOOST_TEST_DYN_LINK, but then I have to copy across the boost test dll (it's not picked up in the manifest by default). 

As far as I can tell, the culprit seems to be the following in <boost/test/unit_test.hpp>

//____________________________________________________________________________//

// ************************************************************************** //
// **************                 Auto Linking                 ************** //
// ************************************************************************** //

#if !defined(BOOST_ALL_NO_LIB) && !defined(BOOST_TEST_NO_LIB) && \
    !defined(BOOST_TEST_SOURCE) && !defined(BOOST_TEST_INCLUDED)
#  define BOOST_LIB_NAME boost_unit_test_framework

#  if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_TEST_DYN_LINK)
#    define BOOST_DYN_LINK
#  endif

#  include <boost/config/auto_link.hpp>

#endif  // auto-linking disabled

// ************************************************************************** //
// **************                  unit_test_main              ************** //
// ************************************************************************** //

namespace boost { namespace unit_test {

int BOOST_TEST_DECL unit_test_main( init_unit_test_func init_func, int argc, char* argv[] );

}}

#if defined(BOOST_TEST_DYN_LINK) && defined(BOOST_TEST_MAIN) && !defined(BOOST_TEST_NO_MAIN)

// ************************************************************************** //
// **************        main function for tests using dll     ************** //
// ************************************************************************** //

int BOOST_TEST_CALL_DECL
main( int argc, char* argv[] )
{
    return ::boost::unit_test::unit_test_main( &init_unit_test, argc, argv );
}

//____________________________________________________________________________//

#endif // BOOST_TEST_DYN_LINK && BOOST_TEST_MAIN && !BOOST_TEST_NO_MAIN

Every time I try to click on a unit test example link I have been getting a 404  error :( Can other people use links like this?

Does it work if BOOST_TEST_MAIN is defined?
