2.15.7 Stuff:

- Now GDM does not save Failsafe GNOME or Failsafe Xterm as the
  user's default session, so the user does not lose their 
  default setting when using Failsafe (bug #341619).  
  (Brian Cameron)

- Updated GDM's slave/daemon message handling so it uses 
  giochannel internal buffering.  This should prevent messages
  from getting lost.  (Ray Strode)

- Performance improvements to gdmsetup start-up.  (Ray Strode)

- Fix for compiling with GCC 2.95.  (Jens Granseuer)

- Translation updates (Beno\303\256t Dejean, Christophe Merlet,
  Lukas Novotny, Ahmad Riza H Nst, Kostas Papadimas, Hendrik
