right now I use those patches and Slackbuild for compiling on my x86 slackware...
change from J to X was inspired by libdv patch doing reverse of this for gcc 4.1:
I also tried 'n' but build was failing too ..
some description for those constraints:

hold on, I am not sure what going on - I tried again with slightly modified cin.Slackbuild and build was failing again until I replaced 'i' with 'X' (anything goes here asm constrain).
it seems to work afterwards - mpeg 2 / 4:2:2 encoding working at 7.5 fps for fullhd vid.. but I want to double-check (uname -m must return i686 for this code to even compile...)

but also due to some asm error in mpeg2enc when I build for i686 target...
I added -fomit-frame-pointer to only mpeg2enc cflags and it compiled... not sure why I was not hit by this earlier, may be because I already had this in cflags?
