When risks of the patch mostly involve type checking or things that
could be caught with a simple compilation, could we relax this
testing requirement to do a cross-build of all-gcc all-target-libgcc
with a recent fully bootstrapped compiler, with -Werror enabled. We
probably then want to make --enable-werror to work for
cross-configurations like stage2/3 in a bootstrap.
With a recent enough native compiler (which for some scenarios implies
that the host compiler needs to be built from trunk too) it should
already work.
Well, it doesn't:

So in make.out I find the first files of gcc after the generators are
built like this:
gcc -c -DUSE_LIBUNWIND_EXCEPTIONS -g -O2 -DIN_GCC

same with --enable-werror=yes .
