Re: operator== missing on std::__debug::map<>::iterator


I'm not discussing if the member operator== is correct or wrong, but
the code compiles fine in several C++ compilers and the only problem I
found was with libstdc++ in debug mode, my point is that it should
either compile or fail in both modes.

Thanks for your responses.

Pedro.
