* ext/tk/tkutil/tkutil.c: improve handling callback-subst-keys. 
  Now, support longnam-keys (e.g. '%CTT' on tkdnd-2.0; however, still
  not support tkdnd-2.0 on tkextlib), and symbols of parameters (e.g. 
  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on; 
  those are attributes of event object). It means that Ruby/Tk accepts
  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but 
  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }". 
  It is potentially incompatible, when user passes symbols to the
  arguments of the callback block (the block receives the symbols as
  strings). I think that is very rare case (probably, used by Ruby/Tk
  experts only). When causes such trouble, please give strings instead
  of such symbol parameters (e.g. call Symbol#to_s method).
* ext/tk/lib/tk/event.rb, ext/tk/lib/tk/validation.rb, 
  ext/tk/lib/tkextlib/blt/treeview.rb, 
  ext/tk/lib/tkextlib/winico/winico.rb: ditto.
* ext/tk/tkutil/tkutil.c: strings are available on subst_tables on 
  TkUtil::CallbackSubst class (it is useful on Ruby 1.9). 
* ext/tk/lib/tk/spinbox.rb, ext/tk/lib/tkextlib/iwidgets/hierarchy.rb, 
  ext/tk/lib/tkextlib/iwidgets/spinner.rb, 
  ext/tk/lib/tkextlib/iwidgets/entryfield.rb, 
  ext/tk/lib/tkextlib/iwidgets/calendar.rb, 
  ext/tk/lib/tkextlib/blt/dragdrop.rb, 
  ext/tk/lib/tkextlib/tkDND/tkdnd.rb, 
  ext/tk/lib/tkextlib/treectrl/tktreectrl.rb, 
  ext/tk/lib/tkextlib/tktable/tktable.rb: disable code piece became 
  unnecessary by reason of the changes of ext/tk/tkutil/tkutil.c.
* ext/tk/lib/tk.rb, ext/tk/lib/multi-tk.rb: change strategy to define
  the constant WITH_ENCODING.
* ext/tk/lib/tk.rb: fix bug on Tk::Encoding.tk_encoding_names.

| To compile 'tcltklib', you must have Tcl/Tk libraries on your environment. 
 | |
| Although 'extconf.rb' script searches Tcl/Tk libraries and header files, 
 | |
| sometimes fails to find them. And then, 'tcltklib' cannot be compiled. If 
 | |
| Tcl/Tk libraries or header files are installed but are not found, you can 
 | |
| give the information by arguments of the 'configure' script. Please give 
 | |
| some or all of the following options. 
 | |
| 
 | |
|  --with-tcltkversion=<version> 
 | |
|       force version of Tcl/Tk libaray
 | |
|       (e.g. libtcl8.4g.so ==> --with-tcltkversion=8.4g)
 | |
| 
 | |
|  --with-tcllib=<libname>       (e.g. libtcl8.4.so ==> --with-tcllib=tcl8.4)
 | |
|  --with-tklib=<libname>        (e.g. libtk8.4.so  ==> --with-tklib=tk8.4)
 | |
| 
 | |
|  --enable-tcltk-stubs          (if you force to enable stubs)
 | |
| 
 | |
|  --with-tcl-dir=<path> 
 | |
|       equal to "--with-tcl-include=<path>/include --with-tcl-lib=<path>/lib"
 | |
| 
 | |
|  --with-tk-dir=<path> 
 | |
|       equal to "--with-tk-include=<path>/include --with-tk-lib=<path>/lib"
 | |
| 
 | |
|  --with-tcl-include=<dir>      the directry contains 'tcl.h'
 | |
|  --with-tk-include=<dir>       the directry contains 'tk.h'
 | |
| 
 | |
|  --with-tcl-lib=<dir>          the directry contains 'libtcl<version>.so'
 | |
|  --with-tk-lib=<dir>           the directry contains 'libtk<version>.so'
 | |
| 
 | |
|  --enable-mac-tcltk-framework  (MacOS X) use Tcl/Tk framework
 | |
|                                (Obsolete. Please use '--enable-tcltk-framework'.)
 | |
| 
 | |
|  --enable-tcltk-framework      use Tcl/Tk framework
 | |
| 
 | |
|  --with-tcltk-framework=<dir>  the directory contains Tcl/Tk framework; 
 | |
|                                "<dir>/Tcl.framework" and "<dir>/Tk.framework".
 | |
|                                When this option is given, it is assumed that 
 | |
|                                --enable-tcltk-framework option is given also.
 | |
| 
 | |
|  --with-tcl-framework-header=<dir>
 | |
|       Tcl framework headers directory 
 | |
|       (e.g. "/Library/Frameworks/Tcl.framework/Headers")
 | |
| 
 | |
|  --with-tk-framework-header=<dir>
 | |
|       Tk framework headers directory 
 | |
|       (e.g. "/Library/Frameworks/Tk.framework/Headers")
 | |
| 
 | |
| 
 | |
|  --with-X11 / --without-X11    use / not use the X Window System
 | |
| 
 | |
|  --with-X11-dir=<path> 
 | |
|       equal to "--with-X11-include=<path>/include --with-X11-lib=<path>/lib"
 | |
| 
 | |
|  --with-X11-include=<dir>      the directry contais X11 header files
 | |
|  --with-X11-lib=<dir>          the directry contais X11 libraries
 | |
| 
 | |
| 
 | |
| If you forgot to give the options when do 'configure' on toplevel
 | |
| directry of Ruby sources, please try something like as the followings.
 | |
| 
 | |
|  $ cd ext/tcltklib
 | |
|  $ rm Makefile
 | |
|  $ CONFIGURE_ARGS='--with-tcl-include=/usr/local/include/tcl8.4/ --with-tcllib=tcl8.4 --with-tklib=tk8.4' ruby extconf.rb
 | |
| 
 | |
| 
 | |
|  *** ATTENTION ***
 | |
| When your Tcl/Tk libraries are compiled with "pthread support", 
 | |
| Ruby/Tk may cause "Hang-up" or "Segmentation Fault" frequently. 
 | |
| If you have such a trouble, please try to use the '--enable-pthread' 
 | |
| option of the 'configure' command and re-compile Ruby sources. 
 | |
| It may help you to avoid this trouble. The following configure 
 | |
| options may be useful.
 | |
| 
 | |
|   --enable-tcl-thread/--disable-tcl-thread
 | |
|   --with-tclConfig-file=<path of 'tclConfig.sh'>
 | |
| 
 | |
| It is not need that 'tclConfig.sh' is a normal Tcl/Tk's tclConfig.sh. 
 | |
| But the file is expected to include the line "TCL_THREADS=0" or "...=1".
 | |
| When no "TCL_THREADS=?" line, if Tcl version is 7.x or 8.0 which is 
 | |
| given by "TCL_MAJOR_VERSION=?" line and "TCL_MINOR_VERSION=?" line, 
 | |
| then --disable-tcl-thread is expected. Else, ignore the 'tclConfig.sh'.
 | |
| If --enable-tcl-thread or --disable-tcl-thread option is given, then 
 | |
| --with-tclConfig-file option is ignored.
