327 If you think configure made a mistake, make sure you are using the latest
328 version from Git. If the latest version fails, report the problem to the
329 libav-user@libav.org mailing list or IRC #libav on irc.freenode.net.
331 if disabled logging; then
333 Rerun configure with logging enabled (do not use --disable-logging), and
334 include the log this produces with your report.
338 Include the log file "$logfile" produced by configure as this will help
345 # Avoid locale weirdness, besides we really just want to translate ASCII.
