I would suggest going a bit further and have:

  #define BOOST_UNUSED_PARAMETER(x)
  void f(int BOOST_UNUSED_PARAMETER(meaningful_name))

so that the Doxygen-generated documentation (e.g. for BoostBook and
QuickBook) contains meaningful parameter names, once we add the
following line to Doxygen's configuration file:

  PREDEFINED = BOOST_UNUSED_PARAMETER(x)=x
