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. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
