        * configure.ac, acconfig.h, daemon/Makefile.am, daemon/gdm.h
          daemon/server.c, daemon/gdmconfig.c, config/gdm.conf.in,
          config/Makefile.am:  Add Xephyr support and fix problem with
          using Xsun Xnest with Xorg 7.2.  Xsun doesn't like font path
          values that have the ":unscaled" suffix.  This required adding
          two new configuration options XnestDisplayArg and
          XnestUnscaledFontPath so that the user can configure whether
          the Xnest command uses the -display argument or the DISPLAY
          environment variable, and to specify whether to strip the
          ":unscaled" bits from the fontpath.  Modified configure so
          that if Xephyr is on the system, it is used as the Xnest
          program since it works better than Xnest.
        * daemon/gdmconfig.h: No longer set default values for the
          configuration...
