[boost] [test] BOOST_PP_VARIADICS is defined twice

Hi, For some reason Boost.Test defines the BOOST_PP_VARIADICS macro, which, I believe, is a macro defined by Boost.Preprocessor. This results in build errors as can be seen here: http://www.boost.org/development/tests/develop/developer/output/teeks99-01b-... I think Boost.Test should not define BOOST_PP_VARIADICS and rely on Boost.PP for that. In any case, BOOST_PP* is not the namespace of Boost.Test.
