To pull it off, I need to ensure the gear that claims to be GCC (by faking __GNUC__), and GCC itself, can handle it. When did GCC add '__attribute__ ((unused))'? We still have GCC 3.x users (IIRC), so we can't break things for them. There is a shinny side to the penny: we don't have to support GCC 2.95. Jeff
