apparently, the patchset for gcc 4.2.1 applies properly to the source for gcc 4.2.2 and gcc 4.2.3. so, if you want, you can simply add support for those last two just by augmenting menuconfig and adding a couple symlinks for those two directories. seems like a cheap way to add a couple new versions.
