2000-04-14  Tor Lillqvist  <tml@iki.fi>

* gtk/gtksignal.c: (Win32:) Export the gtk_private_signals and
gtk_private_n_signals variables, they are used by some software,
sigh.

* gtk/gtkrc.c (get_gtk_sysconf_directory): (Win32:) Fetch the
installation directory from the Registry, where the installer
should have put it.
