I didn't need disable-werror either, which makes me think I'm building a
completely different toolchain to you.

Maybe I'm missing something very obvious?

All I'm doing is cloning from the git mirror, checking out the revisions we've
discussed here and on IRC, creating a new folder out of tree, running
configure, then running make -j41.

  ssh gcc110.fsffrance.org
  git clone git://gcc.gnu.org/git/gcc.git
  cd gcc
  git checkout <hash of revision - I don't have it to hand right now>
  mkdir ../build-gcc
  cd ../build-gcc
  ../gcc/configure --enable-languages=all,ada,go,obj-c++
  make -j41 >& build.log

And that works for me.

If I'm missing a step or an environment variable, I'm happy to try again.
