234 If you think configure made a mistake, make sure you are using the latest
235 version from SVN. If the latest version fails, report the problem to the
236 ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.

240 Rerun configure with logging enabled (do not use --disable-logging), and
