Comment (by TLBettens@…):

 == Warning introduced in release 1_50_0 ==

 Function '''set_option_name''' in class '''error_with_no_option_name'''
 was introduced into file .../boost_1_50_0/boost/program_options/errors.hpp
 causing Visual C++ version 10, perhaps others, to emit the following
 warning message when compiled with warning level 4 (/W4) enabled:

 {{{
 1>c:\boostbuilding\boost_1_50_0\boost\program_options\errors.hpp(253):
 warning C4100: 'option_name' : unreferenced formal parameter
 }}}

 Unused arguments should remain unnamed, and the workaround is something
 like this:

 {{{
 252:        /** Does NOT set option name, because no option name makes
 sense */
 253:        virtual void set_option_name(const std::string& /* option_name
 */){}
 }}}
