My mistake.  You've got to #include <asm/types.h> by hand before the call=
 to=20
#include <linux/videodev.h>.  This is only a problem on systems that have=
=20
v4l2,  And there seem to be two flavors of v4l2 out there causing trouble=
, so=20
it may only be some of them.  Mandrake 9.0 has this problem.
