When I write a callback routine such as those used by X windows,
many times I don't need to use the "client_data" argument.  But
the C++ compiler issues a "unused argument" warning.  I hate to
have warnings generated, so I have been doing stuff like putting
the statement "client_data = client_data;" in the callback simply
to eliminate this compiler warning.  (I hope the optimizer is smart
enought to take this out!).  

Any ideas on how to handle this more elegantly ?
