little patch to get it to compile,
also sets "xset dpms force off" as the default "locker",
because we are using this to turn off the screen (hopefully with the backlight)
to save power/battery life.

Started from HOME/.icewm/startup,
and set-able with set_screen_timeout script.
and linked in to spacefm desktop menu.
(See spacefm doc for source.)



Is called with only one parameter, 
which is the idle time (minutes) before turns off screen:

/usr/local/bin/xautolock -time 8
