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.
