[boost] [test] How to have a simple unit test compile on Borland/CodeGear?

Is the following still a proper way to write a unit test for a Boost 
library component?

   #define BOOST_INCLUDE_MAIN
   #include <boost/test/test_tools.hpp>

   int test_main(int, char*[])
   {
     // TODO Some testing here...
     return 0;
   }

I can't get the above code compiling on the latest Borland/CodeGear 
compiler (Embarcadero C++ 6.21), installed by 
c++builder_2010_3615_win_esd.zip, downloaded from 
www.embarcadero.com/downloads Even though I already patched 
boost/smart_ptr (ticket #4067) and boost/exception (ticket #4068).

I just do:

   bjam toolset=borland

Which tries to compile 
<boost/test/utils/runtime/cla/dual_name_parameter.hpp> apparently, and 
it yields an error at line 43:

     template<typename Modifier>
     void    accept_modifier( Modifier const& m )
     {
         if( m.has( prefix ) ) {
             set_prefix( m[prefix] ); // line 43, "Error E2094"!
             ...

The complete error message is down here. Interestingly, the message says 
that operator+ is missing (while I don't see a need for operator+ in 
this context). Any help is appreciated!

Kind regards,

     Niels
