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...)

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?
