/home/jdm/sdb/servo/src/components/script/dom/bindings/callback.rs:27:39: 27:40 error: obsolete syntax: visibility not necessary
/home/jdm/sdb/servo/src/components/script/dom/bindings/callback.rs:27     pub fn callback(&self) -> *JSObject;
                                                                                                             ^
