When I compile the following simple program on VC6:
Here's a more nicely formatted version (I hope):

    #include <boost/preprocessor/facilities/empty.hpp>
    #include <boost/preprocessor/punctuation/comma_if.hpp>

    #define PARAM(has_param)                    \
        BOOST_PP_IF( has_param, typename Param, \
                     BOOST_PP_EMPTY())
    #define MACRO(has_param)                    \
        template< PARAM(has_param)              \
                  BOOST_PP_COMMA_IF(has_param)  \
                  typename T >                  \
        struct name { };

    MACRO(0)

    int main() {  return 0; }
