Hello all,

Why does Boost.Preprocessor redefines BOOST_PP_VARIAIDCS instead of just
using BOOST_NO_VARIADIC_MACROS from Boost.Config?

Furthermore, GCC supports variadics also when C++11 extensions are not
enabled so I think the following should not && __GXX_EXPERIMENTAL_CXX0X__:

// File: boost/preprocessor/config/config.hpp
#    /* Wave (C/C++), GCC (C++) */
#    elif defined __WAVE__ && __WAVE_HAS_VARIADICS__ || defined __GNUC__ &&
__GXX_EXPERIMENTAL_CXX0X__
#        define BOOST_PP_VARIADICS 1

Thanks.
