It has always been the case that the libgcc ABI cannot change in a
backwards-incompatible way, as this would mean that, for instance, .a
libraries built under an earlier version of gcc would fail to link or
fail to work under a later version.  I really hope the ABI didn't
change, because if it did it will break something.
