Hello,
I am trying to do a LTO bootstrap of the gcc 6 snapshot 20160313 with
../gcc6/configure --enable-languages=c,c++,fortran,ada
--with-system-zlib --enable-nls --without-included-gettext
--enable-checking=release --enable-libstdcxx-time --enable-shared
--enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu
--enable-multilib --with-multilib-list=m32,m64 --enable-libgomp
--enable-libcilkrts --enable-lto --with-isl --enable-libsanitizer
--with-build-config=bootstrap-lto
where Gentoo will use (truncated)
--enable-languages=c,c++,fortran,ada --enable-obsolete
--enable-secureplt --disable-werror --with-system-zlib --enable-nls
--without-included-gettext --enable-checking=release
--enable-libstdcxx-time --enable-shared --enable-threads=posix
--enable-__cxa_atexit --enable-clocale=gnu --enable-multilib
--with-multilib-list=m32,m64 --disable-altivec --disable-fixed-point
--enable-targets=all --disable-libgcj --enable-libgomp
--disable-libmudflap --disable-libssp --enable-libcilkrts --enable-lto
--with-isl --disable-isl-version-check --enable-libsanitizer
--with-build-config=bootstrap-lto
(what failed for me in stage of gnattools - no rule to make target ...).
It stopps with:

Should it work without using --disable-werror at ./configure please?
