 // Define a subset of the CoreWLAN interfaces we require. We can't depend on
 // CoreWLAN.h existing as we need to build on 10.5 SDKs. We can't just send
 // messages to an untyped id due to the build treating warnings as errors,
 // hence the reason we need class definitions.
 // TODO(joth): When we build all 10.6 code exclusively 10.6 SDK (or later)
 // tidy this up to use the framework directly. See http://crbug.com/37703
