clang understands -Werror as well.

I think you can turn it on for bootchecks by default, with an option to
disable it. Different compiler versions will often warn about different
things, sometimes important but sometimes relatively harmless things.
It should be possible to continue testing while (knowingly) ignoring
warnings.

Actually, the warning I have in mind is not only harmless but spurious:
for a while, gcc used to complain about local variables shadowing
globals.
