Add dependency on Atk for accessibility support.

Thu May  3 14:13:49 2001  Owen Taylor  <otaylor@redhat.com>

        * INSTALL.in HACKING gtk/gtkaccessible.[ch] gtk/gtk.c: Add
	dependency on Atk for accessibility support.

	* configure.in **/Makefile.am: Major reworking of substituted
	variables for CFLAGS/LIBS to make a lot more sane and
	keep the the compile/link lines a bit shorter.

	* gdk/x11/gdkkeys-x11.c: Fix #endif with trailing stuff.
