Hi, I'm using a few day old RC_1_34_0 from cvs. In boost\function\function_base.hpp I get a warning message that is quite annoying so I went in to remove it. The thing is I don't understand what it is complaining about. It gives this warning message: boost/function/function_base.hpp(287) : warning C4189: 'out_functor' : local variable is initialized but not referenced But the code is: functor_type* out_functor = reinterpret_cast<functor_type*>(&out_buffer.data); // Some compilers (Borland, vc6, ...) are unhappy with ~functor_type. out_functor->~Functor(); which looks a lot like it is referencing out_functor to me.. can this warning be disabled This warning shows up in several places like when compiling program options source. Although we don't have a strict 0 warning policy the simple line: boost::signal< void () > g_signal; generates a 83 line warning message for me which makes it much more difficult to glance at the output window and find helpful warnings. Thanks, Michael Marcin
