New features in version 0.8.4:

- class list input file is automagically created from header files

- examples should now build without problems with glibc2

- configure.in: use `-pthread' option of gcc if available
		build debug version with `--enable-debug'

- GToolKit should now work with multiple threads (with NSThread)
  (if your libc, libobjc, libX11 and libgtk/gdk/glib support that;
   since gtk+-1.0.x does not, threads currently cannot be used...)

- configure.in: test for <unistd.h> and getcwd()

- html/*: updated the documentation for gtk+-1.0.6

- GTKAction.m: added check for invalid selector

- GTKMenuFactory.in: allow objc method selectors in GtkMenuEntry

- GTKWindow.in: several new notifications:
  WindowDidBecomeMain, WindowDidResignMain,
  WindowWillOpen, WindowWillClose

- GTKApplication.[hm]: several new notifications:
  ApplicationDidBecomeActive, ApplicationDidResignActive,
  ApplicationWillFinishLaunching, ApplicationDidFinishLaunching,
  ApplicationWillTerminate

- GTKApplication now maintains the application's window list and
  main window (like NSApplication in OpenStep)

- GTKApplication allows more event loop control
  (isRunning, modal windows...)

- Examples/windows.m: new sample program (to test all the new features)

- several small bugs fixed
