No argument there. In some sense, we're in that happy place now
already - i.e. it is simplified, when C++11 is assumed:

    #ifndef BOOST_NO_CXX11_STATIC_ASSERT
    #  ifndef BOOST_NO_CXX11_VARIADIC_MACROS
    #    define BOOST_STATIC_ASSERT( ... ) static_assert(__VA_ARGS__,
#__VA_ARGS__)
    #  else
    #    define BOOST_STATIC_ASSERT( B ) static_assert(B, #B)
    #  endif
    #else

Everything after that #else is just padding bytes anyway. :)
