  I think an idiomatic solution is :

    int unused ;
    unused ;

Rene Rivera proposed this:

  namespace boost { namespace detail {
      inline void no_unused_variable_warning(void*) { }
  } }

  #define BOOST_NO_UNUSED_VARIABLE_WARNING(v) \
      ::boost::detail::no_unused_variable_warning(&(v))

See
namespace boost { namespace detail {
    inline void no_unused_variable_warning(void*) { }
} }
