-if u notice errors in the align stuff, need more alignment for some asm code for some cpu
-or need to use a function with less aligned data then send a mail to the ffmpeg-dev list, ...

-!warning these alignments might not match reallity, (missing attribute((align)) stuff somewhere possible)
-i (michael) didnt check them, these are just the alignents which i think could be reached easily ...
