+dnl It is hard to find a good test on how to check the correct
+dnl inotify version. They changed the headers a lot.
+dnl in kernel 2.6.13 __NR_inotify_init was added to the defined syscalls
+dnl in asm/unistd.h and IN_MOVE_SELF was added to linux/inotify.h
+dnl so with this check you need a very new kernel and kernel-headers!
