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.

4 Subject: Patch for cross compiling s/390 kernel on linux host
5 Date: Tue, 31 Aug 2004 15:45:41 +0200
9 I had big problems compiling a kernel for s/390 on my linux host - I tried
10 different chains from crosstool-0.28-rc34 and finally succeded with
11 gcc-3.3.4-glibc-2.3.2 after applying another patch to binutils-2.15
13 All compilations of the different kernel versions I tried stopped with
14 "Invalid .insn format" somewhere. I checked the recent cvs version of
15 binutils and applied the latest diff to gas/config/tc-s390.c and that solved
