How do I use the gcc "__attribute__" (1)correctly in a Objective-C declaration?

Sadly, you can't -- __attribute__ isn't part of the ObjC syntax (that is, you can't apply it to classes, protocols, methods, ivars, etc. -- it still works on plain C in a .m file).

I hacked a copy of the compiler once upon a time to support printf- style format checking on +[NSString initWithFormat:] and friends and had to add this to the grammar. Since then, the compiler's parser has moved from flex/bison to a hand written parser (at least, I think this is integrated in the 4.1 tree; not sure).
