I said above the compiler I'm using, which is kgcc. =P AFAICT, a 2.96 kernel wouldn't even boot properly (well, I listened to others, so I've only had the benefit of *other* people's experience!).

I'll give your patch a try on the morrow, or day after. Gotta get my new Visor working w/USB cradle first! I just wanted to find out if those messages indicated a problem, or if they are harmless. Personally, I hate seeing even warnings--I'd rather the code compiled without any at all (although with some compilers, that's just not possible!!).
Thanks for the reply.
