What are these missing headers? Because if they aren't necessary then they can
be removed from gcc-common.h. There were missing headers on arm/arm64 and these
archs are supported. I think this version check is unnecessary because
gcc-plugin.sh also checks the missing headers.
rs6000-cpus.def, included via tm.h - see

I realise gcc-plugin.sh does detect this, but the point of the
additional version check is to provide somewhat more helpful advice to
the user.
What is the problem on gcc-4.5/gcc-4.6?
On 4.6.4, c-family/c-common.h:
/scratch/ajd/gcc-test-v2/kernel/scripts/gcc-plugins/gcc-common.h:60:31:
fatal error: c-family/c-common.h: No such file or directory
ajd@ka1:/scratch/ajd/tmp/cross/gcc-4.6.4-nolibc/powerpc64-linux$ find
-name c-common.*
./lib/gcc/powerpc64-linux/4.6.4/plugin/include/c-common.h
./lib/gcc/powerpc64-linux/4.6.4/plugin/include/c-family/c-common.def
Are we sure the version check in gcc-common.h:59 is correct, or is this
just a peculiarity of my particular toolchain?
I need to build another 4.5 toolchain, I'll try to do that this week.
