The biggest source of changing warning numbers that I'm aware of
comes when you switch abi's from o32 to n32 or n64, since the front
ends used are different. As far as I know,
the warning numbers never overlap, this was a definite issue of
concern. It is a pain, but trying to map the old warnings to the new
warnings was even more of a pain, since there wasn't really a 1-1
correspondence.
