Actually I think this is the way it gets mangled on Darwin, I think it
gets mangled differently on any other target as the other targets
actually mangle the message name instead of keeping it as "+[Foo
bar:]".

So you might want to double check what happens under Linux with the
objective-C++ front-end also.
