Don't do that. It is not possible to make autoconf warning-free for all
possible compilers. So our advice has always been to probe for -Werror
independently from other compiler flags, and add it in at the last
minute, but NOT to expect configure to be running with -Werror in effect.
That said, if you have a simple patch that reduces one case of false
test results due to -Werror, we can still probably apply it.
