In 2.4-9.1.93, videodev2.h, dvb/osd.h and dvb/video.h contain references to __user which is not defined and AFAICT is not needed outside of the kernel. This obviously causes builds needing those headers to fail, for example that of http://www.cadsoft.de/vdr/ . The attached patch, to be applied to the patches in CVS :P, fixes it here.
