This breaks compilation on Debian Etch x86_64. I'm unsure if this is 
expected behavior though.

I applied (in order):

vc1dsp_c_cosmetics.diff
vc1dsp_c_macroify.diff
vc1dsp_c_proto.diff
vc1dsp_mmx.diff

If i build with --enable-gpl --enable-pp --enable-pthreads 
--enable-libx264 --cpu=nocona --disable-dv1394 --enable-libvorbis 
--enable-libogg --enable-libxvid --enable-libmp3lame --enable-liba52, 
the error is:
