No, that is already disabled by default as far as I know, we are talking
about another patent: U.S. Patent 4,698,672
will expire on *October 27, 2006.*
Also I'd also like to explain that this lib was never used. It did only
import it into /vendor and not into /trunk/reactos/lib, so a revert of
my delete would be pointless if none wants to write code that uses it. I
do have imported it in my working copy, together with a almost done
patch for jpeg-wallpaper loading, but I have decided not to commit it
until *October 27, 2006.
