Just some notes to this...

My project is using ffmpeg and I have been trying to get it to compile on 
Fedora Core 4 i386 (gcc 4.0.2). With current cvs I get errors:

In file included from i386/dsputil_mmx.c:2492:

With gentoo patch posted here earlier:
/tmp/ccyR2jDE.s: Assembler messages:
/tmp/ccyR2jDE.s:7775: Error: suffix or operands invalid for `dec'
/tmp/ccyR2jDE.s:9417: Error: suffix or operands invalid for `dec'

/tmp/ccyR2jDE.s:16679: Error: suffix or operands invalid for `dec'
make[4]: *** [dsputil_mmx.lo] Error 1

After that I took the libavcodec/i386 dir from xine cvs which seems to work.
