No... The kernel (on 32 bit systems) just doesn't support 64-bit
handling at all... In my version, this piece of code also gives problems
(the part where I compare 64 bit numbers, for VIDIOC_[SG]_STD). Maybe
you can help a bit here, I didn't look at this for a few days now. Try
changing the comparing of 64 bit numbers to 8-byte memory comparisons,
so using __u64 a, b; memcmp(&a, &b, sizeof(__u64)); instead of (a ==
b);. Totally untested, but it'll probably get rid of the compiler error
too...

/me is clueless about why the kernel has broken support for 64bit
stuff... Guess I should look at BTTV-0.9...
