Owen Taylor 2cabeeb1c3 Removed g_object_pointer_hash, which was just g_direct_hash.
Tue Jun  9 18:44:57 1998  Owen Taylor  <otaylor@gtk.org>

	* gtk/gtkobject.c: Removed g_object_pointer_hash, which
	was just g_direct_hash.

Mon May 25 19:54:20 1998  Owen Taylor  <otaylor@gtk.org>

	* configure.in: x_libs=, not $x_libs=. Enough said.
          (Case only hit for --disable-xshm)

Mon May 25 12:08:14 1998  Owen Taylor  <otaylor@gtk.org>

	* configure.in (LDFLAGS): Add to $CFLAGS and $LDFLAGS
	  when testing for X libraries, don't replace them. Because
	  the user might have specified the path to the X libraries
	  themself before running configure.

	* examples/**.c: Changed all gpointer * to gpointer

Sat May 23 21:54:05 1998  Owen Taylor  <otaylor@gtk.org>

	* configure.in (LDFLAGS): Bomb out with a moderately
	  helpful message if detection of X libraries fails.

Sat May 23 18:57:06 1998  Owen Taylor  <otaylor@gtk.org>

  [ Combination of:
     gtk-rrh-980412-0.patch (Raja R Harinath <harinath@cs.umn.edu>)
     gtk-jbuhler-980516-0 (Jeremy Buhler <jbuhler@cs.washington.edu>) ]

	* gdk/gdk.h gdk/gdkcc.c gdk/gdkfont.c gtk/gtkmain.c
	  gtk/gtksignal.c gtk/gtktext.c:

	  Fixups for warnings from adding const to type of GHashFunc,
	  GCompareFunc

	* gtk/gtkcombo.c (gtk_combo_entry_key_press): Minor style/
	  ansi-warnings fixups.

Tue Jun  9 17:47:33 1998  Owen Taylor  <otaylor@gtk.org>

	* glib.h: Remove #error - HP/UX.

Sat May 23 19:00:01 1998  Owen Taylor  <otaylor@gtk.org>
  [ Combination of:
     gtk-rrh-980412-0.patch (Raja R Harinath <harinath@cs.umn.edu>)
     gtk-jbuhler-980516-0 (Jeremy Buhler <jbuhler@cs.washington.edu>) ]

	* glib.h ghash.c gstring.c gdataset.c gutils.c:
	- Added new typedef g_const_pointer; expunged all incorrect
	  uses of 'const gpointer'.
	- Fixed up warnings that that created,
	- Changed GHashFunc and GCompareFunc to take g_const_pointer
	  arguments. (Necessary, but will cause warnings in existing
	  code until fixed)
	- Added other new const in harmless positions.
