Err..., asm/ is just the arch-specific part of the kernel headers, and
equally fragile therefore. So the signal.h detour doesn't buy you
anything.
Now, for the specific problem of videodev.h, the kernel happens to be
the one and only source providing an application interface--there's no
standard library inbetween. Hence, the videodev headers are actually
meant to be used from userspace, and it's a bug if they break in
userspace. Incidentially a bug that has been fixed in the latest
linux-kernel-headers package (that unfortunately failed to build on a
couple of archs). So you can either copy the fixed headers from there,
or Build-Conflict with linux-kernel-headers (<< 2.5.999-test7-bk-10).
