This syntax is only supported as of gcc 4.5.0 [1,2].

If this is in an internal header, that's okay. If this header is
installed and meant to be included by third-party developers, then
change it to 'deprecated' without the message. This syntax should be
valid for gcc 4.2.1 [3]; hopefully even in the Apple patched version.
