 A. Link the main Python binary with C++.  Change the definition of
 LINKCC in Modules/Makefile to be your C++ compiler.  You may have to

 A. Tkinter.py (note: upper case T) lives in a subdirectory of Lib,
 Lib/tkinter.  If you are using the default module search path, you
 probably didn't enable the line in the Modules/Setup file defining
 TKPATH; if you use the environment variable PYTHONPATH, you'll have to
 add  the proper tkinter subdirectory.
