Not use -Werror. Seriously, it is impossible to get all configure tests to be effective, efficient, portable, and warning-free for all kinds of useful and useless compiler warning flags from all kinds of compilers and compiler versions. We've been fixing a few instances that could be improved without greater harm, but with some it just seems impossible to do. Just add -Werror at 'make' time if you need to use it. You can also think about using Automake-1.11's silent-rules option, some people say it helps them see warnings stand out more from the build log (but a good editor that parses 'make' output does just as well). Hope that helps. Cheers, Ralf _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
