I'm getting the following 2 errors when compiling on CentOS 7:
gitbrowser.c:1319:53: error: 'GtkDialog' has no member named 'action_area'
gtk_box_pack_start(GTK_BOX(GTK_DIALOG(qoi->dialog)->action_area), hbox, TRUE, TRUE, 0);
gitbrowser.c:1320:56: error: 'GtkDialog' has no member named 'action_area'
gtk_box_recorder_child(GTK_BOX(GTK_DIALOG(qoi->dialog)->action_area), hbox, 0);
