ruby--ruby/ext/tk/stubs.c
nagai c9ec812897 * ext/tk/tcltklib.c: cannot compile for Tcl7.6/Tk4.2. 
* ext/tk/tcltklib.c: add nativethread consistency check.
* ext/tk/stubs.c: ditto.
* ext/tk/lib/tk.rb: forgot to define TclTkIp.encoding and encoding=
  when Tcl is 7.6 or 8.0.
* ext/tk/lib/tk/wm.rb: support to make some methods as options of
  root or toplevel widget. [ruby-talk:150336]
* ext/tk/lib/tk/root.rb: ditto.
* ext/tk/lib/tk/toplevel.rb: ditto.
* ext/tk/lib/tkextlib/SUPPRT_STATUS: update RELEASE_DATE
