I'm having some difficulty building Asterisk in Rawhide now that GCC has been upgraded to 4.3. As you can see from [1] the build error out because of some undefined symbols (__sync_fetch_and_add_4 and __sync_sub_and_fetch_4). From what I've been able to figure out from googling around is that these two functions are no longer available when building with '-march=i386' because i386 processors don't have the atomic operations that are required. The "solution" that I have seen proposed is to build with '-march=i686'. Unless someone has some other solution, I'd like to start building Asterisk as i686 in Rawhide rather than i386.
