 This code


 {{{
 #include <boost/program_options/errors.hpp>

 int main(int, char *[]) { return 0; }
 }}}

 compiled with


 {{{
 gcc -I/path/to/boost -c -Wunused-parameter -Wshadow test.cxx
 }}}

 produces a warning about an unused parameter and several warnings about
 shadowed class members:

 {{{
 /opt/local/include/boost/program_options/errors.hpp:253: warning: unused
 parameter 'option_name'
 /opt/local/include/boost/program_options/errors.hpp: In constructor

 }}}

 This was compile on Mac Snow Leopard, gcc 4.2.1 with the boost
 distribution from macports (although I doubt any of that matters).
