It is not. For DMD 2.012, it is:

     int opCmp(Object o)
     {
	// BUG: this prevents a compacting GC from working, needs to be fixed
	//return cast(int)cast(void *)this - cast(int)cast(void *)o;

	throw new Error(cast(string) ("need opCmp for class "
                                       ~ this.classinfo.name));
     }


It's also the same in DMD 1.023 (except without the string cast).
