This problem happens because the v4l/config-compat.h includes the
linux/autoconf.h . This file is generated by v4l/scripts/make_config_compat.pl .

I found different commits where the inclusion of this file was
completely removed, like in
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=911f21501f50b16ce77f37b01e90b5b73c8c80bf .
I doubt whether the line should be completely deleted or a construct
like this should be used:

#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 33)
#include <linux/autoconf.h>
#endif

What do you think?
