Yes. In FreeBSD 4.x, gcc was patched not to warn about these, so compiling with -Werror was possible even when using this. Since FreeBSD 5.x, this patch wasn't applied anymore. If you only want it to compile on your own system with -Werror, you can use this patch (and probably adapt it to %c, %x and %X as well): http://www.stack.nl/~marcolz/FreeBSD/gcc-strftime-format-freebsd7.patch.txt Marc
