I'd suggest working on it in your working copy, and not checking into CVS
for a day or so.  I have some ideas as to how a project like this can deal
with multiple optimizations (for different processors, etc.), but I need
to think about them a bit and go over the code as it's structured now.

That said, I think creating vlc_x86.[ch] with identical contents to the
standard vlc.[ch] except for the code itself is a good place to start.
We'll want to come up with some combination of stuff that allows a
Makefile to select one or the other without having to duplicate tables and
such.

I'll post tomorrow sometime on my ideas for this.

I'd be very interested in taking a peek at what you get as soon as you get
something working, though, regardless of CVS.
