I actually had done the symbolic link from /usr/src/linux/include/linux to
/usr/include/linux before I wrote my original message.  That fixed some of the
compile errors I was having, but introduced the ones I mentioned.  Now, at the
advice of d18c7db, I moved the linux/videodev.h include statement to the top and now
I get 2-3 times as many redefinitions:

In file included from /usr/include/bits/fcntl.h:25,

Anyone have any other suggestions?
