/* minimum alignment rules ;)
If you 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 libav-devel mailing list, ...
+to the ffmpeg-devel mailing list, ...
!warning These alignments might not match reality, (missing attribute((align))
stuff somewhere possible).
