Bugzilla Bug 193061

gdm failed to compile on two of my machines because a dependency wasn't at a
particular version.  Here is a summary of the failed compile log:

gdmsetup-gdmsetup.o: In function `combobox_changed':
gdmsetup.c:(.text+0x443a): undefined reference to `g_hash_table_remove_all'
gdmsetup-gdmsetup.o: In function `command_apply':

!!! If you need support, post the topmost build error, and the call stack if
relevant.
!!! A complete build log is located at
'/var/log/portage/gnome-base:gdm-2.18.4:20070919-125644.log'.

This particular function wasn't introduced until >=dev-libs/glib-2.12*  After
updating glib I was able to compile gdm.  The ebuild shows a required
dependency of >=dev-libs/glib-2.8, this needs to be updated.

Reproducible: Always

Fixed.  Good catch.
