Thanks a lot. Committed.

I'd like to call for volunteers who'd have the brainpower and competence
(I unfortunately lack ASM knowledge here) to fix the following files:

* libmpcodecs/native/RTjpegN.c (lots of assembler error messages: suffix
or operands invalid for pretty much all calls of `psubw', `punpcklwd',
`movq', and `paddw'. All other gcc version compile with no warning at
all)

* postproc/swscale_template.c (memory inputs not directly addressable.
Fixes for thoses files might look like those for libavcodec that have
been flying around ffmpeg's mailing list)

* liba52/imdct.c (memory inputs not direcly addressable. Same as above)

... and that's it!

You you need gcc's output, either refer to my previous message or I
guess I can re-post them if needed.

Patches are thus welcome. I'd gladly test them.

Regards,
Guillaume
