In the Linuxfromscratch project, we simply installed the above
(roughly) as sys/inotify.h with glibc-2.3.6 and patched our older
kernel headers to include linux/inotify.h and add the necessary
syscalls. Everything has been working fine for me, and I have a few
programs using inotify such as gamin, gnome-vfs and dovecot. Here's
the exact patch we used for sys/inotify.h (you have to install it
yourself):
