Hi William
For the last couple of builds , I have been using GCC-4.7.0 with an
arch patch so it recognises cloog-0.17 and isl-0.09. is working well
so far, just tried ppl 0.12 as well, so far no problems, but I lack
the courage and documentation to full utilise the graphite.
ops.
For GCC-4.7.0 i had to redo the pure patches and used the following
flags --disable-build-with-cxx --disable-build-poststage1-with-cxx
--with-native-system-header-dir=/tools in building the cross compiler
which got rid of the impure headers warning and enable me to delete
the line where we adjust the start file include prefix
However i had to disable stack smashing protection when constructing
the final libc library in 10.7 other wise it wouldn't build
Other problems encounted were when I upgraded to util-linux-2.21, as
I use the boot method (cross compile from an earlier x86 build to
pure x64), the login utils now have a PAM dependency , so i cheated
and used the earlier versions copy, probably want to cross compile
shadow, but I couldn't get it to work correctly.
cheers
Martin

For final libc if you want to use fstack-protector-all first build
the libraries without that by adding build-programs=no in configrams,
then directly build again with build-programs removed and add your
CFLAGS for fstack-protector-all and whatever else. That should work.
Worked for Robert back in the day with his hardening builds!
