Thanks guys!

Dominik and Emanuele, I'm very interested in your feedback on my patch
esp. as you've worked on liba52 in mplayer.

That is essentially what I'm aiming at.  However, the I think the local
diff needs to be reorganized too, at a minimum by moving optimized
versions into separate files, one per (similar to libmpeg2, actually).
The rest of what I've done is putting function pointers in a52_state
instead of making them global, avoiding the duplication (triplication)
of a52_downmix, and consistent naming.

Yes, sort of.  There is an alpha (beta?) integer-arithmetic version in
svn.  I'm not sure it is fully functional.  Not much recently, I guess.
I wrote a CRC-checking patch based on some older (libac3) code, that
should be merged soon.  I've also some ideas about a new API
(backwards-compatible, of course ;)
