This is a program I found buried in BSD ports. Source header looks like MIT license. Its purpose is to run a specified program if there is no user input to the X server after a specified period of time; useful for having your system automatically go into hibernation on its own if you leave it alone for a while. With removal of "__dead" in the source code it compiled with gcc-4.3.2 and works as expected on xorg-server-1.3.0.0-r6. I found it here: ftp://ftp.freebsd.org/pub/FreeBSD/ports/local-distfiles/novel/xidle-24102005.tar.bz2 If desired I could write up an ebuild in the next few days.
Created attachment 171506 [details, diff] Make compilation possible.
Created attachment 171507 [details, diff] Including (OpenBSD) Makefile replacement
I like it.
Fixed. Thanks for reporting.
