Quoting Paolo Bonzini <bonz...@gnu.org>:
--enable-werror-always is today what you're looking for, I think.
I just tried, and it seems to work for my i686-pc-linux-gnu X ia64-linux-gnu build. Not only did it supply -Werror, make all-gcc already completed, while the bootstrap on gcc60 has been chugging along from since before I started this discussion. So, back to the original question. Is this a suitable bootstrap substitute for testing patches?
