Package: linux-kernel-headers Version: 2.5.999-test7-bk-15 In /usr/include/linux/jiffies.h line 16, 20 and 22 it uses the u64 type. That type is __KERNEL__ only. I think the whole file should be probably be #ifdef'd to __KERNEL__ but I'm not sure. This problem causes a build failure for sysklogd and should therefor probably be tagged as RC. Kurt
