/*
 * In the Apple runtimes, objc_msgSend() and objc_msgSendSuper() are
 * trampolines that should be cast to the type of the IMP and then called.  
 *
 * The GNU runtimes do not have these trampolines.  When sending a message with
 * one of these runtimes, you must call objc_msg_lookup[_super]() and then call
 * the returned function pointer.  We define a set of trampolines for the
 * correct types here, and #define them all back to the runtime-provided
 * trampoline for the Mac runtimes.
