Several Problems with SVN build

[David Ronis <ronis ronispc chem mcgill ca>]

I'm having several problems with today's svn build.

1.  The new freedesktop/PolicyKit doesn't build on my Slackware-11.0
box.  I get the following error:

polkit-context.c:38:25: error: sys/inotify.h: No such file or directory

followed by a slew of declaration warnings.  I manually copied
sys/inotify.h from a Slackware 12.0 box that can build PolicyKit.  This
removes the error, but I get unresolved extern errors (not
surprisingly). 

2.  On my Slackware-12.0 box, PolicyKit builds, but hal doesn't. I get:

hal-setup-keymap.c: In function 'main':
hal-setup-keymap.c:143: warning: implicit declaration of function
'lookup_key'
hal-setup-keymap.c:143: warning: nested extern declaration of
'lookup_key'
hal-setup-keymap.c:143: warning: assignment makes pointer from integer
without a cast
hal-setup-keymap.c:145: error: dereferencing pointer to incomplete type

2.  On the Slack-11.0 box, gnome-system-tools doesn't build:

/home/ronis/Project/notar/GNOME/garnome/desktop/gnome-system-tools/work/main.d/gnome-system-tools-2.21.1/src/users/group-settings.c:338: undefined reference to `oobs_group_set_name'
