I don't know if anyone is currently interested in deprecation warnings with GCC 12, but I'm seeing messages like:

/builddir/build/BUILD/kicad-6.0.1/include/hashtables.h:36:25: warning: 'template<class _Arg1, class _Arg2, class _Result> struct std::binary_function' is deprecated [-Wdeprecated-declarations]

and

/builddir/build/BUILD/kicad-6.0.1/include/hashtables.h:80:29: warning: 'template<class _Arg, class _Result> struct std::unary_function' is deprecated [-Wdeprecated-declarations]

when building with GCC 12.  I'm not a C++ developer so I don't know how significant these are.

A full log is available here:  https://kojipkgs.fedoraproject.org//work/tasks/7031/81867031/build.log

Should I write this up as an issue, or should it be ignored for now?
