Re: [PATCH] Silence PPC+ARM preprocessor warnings in atomicity.h

[Benjamin Kosnik <bkoz at redhat dot com>]

Awesome. Please check this in. I posted my linux-ppc testresults here:

http://gcc.gnu.org/ml/libstdc++/2000-11/msg00419.html

If you could try to verify these results, CVS after your patch, and post 
your mkcheck.txt file to the libstc++ list I'd appreciate it.

It looks like x86/alpha/powerpc are now in sync, which is cool. I'm 
working on an arm cross compiler at the moment, but if you can post arm 
native results I'd appreciate it.

thanks,
benjamin
