 dnl It's 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!
 dnl On my gentoo, /usr/include/asm and /usr/include/linux are no symlinks
 dnl into the current kernel tree....so i also try to find the includes
 dnl under /usr/src/linux or under /usr/include/linux-`uname -r`
 linux_rev=`uname -r`
