Version numbers when they are *meant* to check features. Writing and
maintaining complex brittle configure tests is a waste of time. Even if
someone is willing to waste their time writing the tests, the maintainance
burden will still fall on the core VLC developers. This is unacceptable to
me.

If both libav and FFmpeg had internally consistent but externally
conflicting version numbers, we could have a long flame war about which
numbers to use. Currently only libav has consistent version numbers so the
subject is moot; VLC follows libav version numbers.

The potential solutions and work-arounds have already been discussed on
this mailing list and IRC, so I will not go through them again.
