Robert P. J. DAY says:
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.

14 incompatible with our later declaration, perhaps by using const
15 attributes. So we hide the declaration in errno.h (if any) using a

18 #define sys_errlist sys_errlist__
