* 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.

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.

* 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.
