README: changed URL format to <URL:...>; added section on Tk.

Makefile.in: run config.status in "make recheck".
configure.in: add test for hypot().
config.h.in, configure: since configure.in changed.
rest: the usual boring stuff.

+The Tk extension
+----------------
+
+Tk (the user interface component of John Ousterhout's Tcl language) is
+also usable from Python.  Since this requires that you first build and
+install Tcl/Tk, the Tk interface is not enabled by default.  It
+requires Tcl 7.3 and Tk 3.6.  For more info about Tk, including
+pointers to the source, see John Ousterhout's home page at
+<URL:http://playground.sun.com/~ouster/>.
+
+To enable the Python/Tk interface, once you've built and installed
+Tcl/Tk, all you need to do is edit two lines in Modules/Setup; search
+for the string "Tk".  Un-comment one (normally the first) of the lines
+beginning with "#tkinter" and un-comment the line beginning with
+"#TKPATH".  (If you have installed Tcl/Tk in unusual places you will
+have to edit the first line as well to fix the -I and -L options.)
+See the Build Instructions above for more details.
+
+There is little documentation.  Begin with fetching the "Tk Lifesaver"
+document, e.g. <URL:ftp://ftp.cwi.nl/pub/python/tkinter-doc.tar.gz> (a
+gzipped tar file containing a PostScript file).  There are demos in
+the Demo/tkinter directory, in the subdirectories guido, matt and www.
+
+Note that there's a Python module called "Tkinter" (capital T) which
+lives in Lib/tkinter/Tkinter.py, and a C module called "tkinter"
+(lower case t) which lives in Modules/tkintermodule.c.  Demos and
+normal Tk applications only import the Python Tkinter module -- only
+the latter uses the C tkinter module directly.  In order to find the C
+tkinter module, it must be compiled and linked into the Python
+interpreter -- the tkinter line in the Setup file does this.  In order
+to find the Python Tkinter module, sys.path must be set correctly --
+the TKPATH assignment in the Setup file takes care of this, but only
+if you install Python properly ("make install libinstall").  (You can
+also use dynamic loading for the C tkinter module, in which case you
+must manually fix up sys.path or set $PYTHONPATH for the Python
+Tkinter module.)
