Hi all,

Here’s a fix for another breakdown in communication between GNOME and
elogind.  With this patch, I can power down my machine from GDM.  The
gnome-session patch comes from Gentoo.  On one hand, it’s not perfect.
It sets the “HAVE_SYSTEMD” flag, causing gnome-session to try and talk
to systemd for things that have nothing to do with logind.  On the other
hand, this isn’t a regression for us.  It’s essentially how we did it
before (if you run GDM or GNOME, check your logs: gnome-session is
complaining about systemd).
