The v4l headers aren’t #included on non-Linux systems, so the v4l_* functions aren’t found.

I’ve now solved this problem simply by removing the #defines of __u64 and __s64 everywhere in the code. It seems videodev2.h (which is #included by videodev.h) is adding the typedefs for compatibility, but breaks code which does the #defines by itself. :/
So: Kopete now compiled successfully, supposedly with V4L2 support, but I still cannot add a webcam. Is there a way to tell kopete which device to use? Or are there further modifications required?
