Milestone:  Boost 1.39.0        |   Component:  parameter
  Version:  Boost 1.38.0        |    Severity:  Problem  
 Keywords:  -Wunused-parameter  |

 Hi, the BOOST_PARAMETER_FUNCTION macro leaves a helper function with the
 parameter boost_parameter_enabler_argument around. however, that parameter
 is never used, so gcc with -Wunused-parameters leads to really ugly
 template infested warnings that the user has no control over. I suggest
 therefore either to remove the name of the parameter entirely (or rather
 comment it out for documentation purposes), or if this is not supported by
 all compilers (gcc 4.2-4.4 do work here) to have this parameter casted to
 void in the function body.
