    HelperList: Don't use ifndef GLIBMM_DISABLE_DEPRECATED around this.
    
    To avoid breaking the gtkmm-2.24 build with --enable-warnings=fatal,
    and the build of apps that do this too.
    However, those apps (Inkscape) need to stop using that ancient
    deprecated version of gtkmm.
    Bug #752797
