--- Comment #1 from Franz Sirl <sirl at gcc dot gnu.org> ---
Can be worked around by bootstrapping with --disable-werror. Last reconfirmed
with trunk r246380. Trunk is at 7.0.1, so --disable-werror is the default right
now.

I guess the only real question is if the profile-based optimization is doing
the right thing here.
