It'd be great to see autoconf-2.60 soon, but do bear in mind that running configure with CFLAGS='-Wall -Werror' is extreme: using -Werror makes the process very fragile. I've found it useful to configure with banal options, and then to compile with stricter ones like those, but even then, I use -Werror only on recent glibc/Linux-based systems. Sometimes, especially in autoconf code snippets, it's best not to try to remove all compile warnings. Of course, if your using -Werror exposes easy-to-fix warnings, e.g., about obviously unused variables, that's great and we should fix them. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
