[Python-Dev] Upgrading tcl/tk deps

Yes. There is a set of changes that you need to preserve. Tk *never*
works with any recent VC compilers, so even if you use a new version, you
still likely have to adjust the sources and the build process. Also, make
sure Tix works.

So there are two options:
a) adjust the existing sources to work with the new compiler. To do so,
    modify tk-8.5.9.x (or whatever we currently use), then tag your  
modifications
    as tk-8.5.9.<next> (would be .1 AFAICT), then update Tools/buildbot and
    PCbuild/readme.txt to refer to these.
b) import new sources into tk-8.X.Y.x, then go through the changes in  
tk-8.5.9.x,
    and port over what is still needed. Again, tag your imported tree so that
    the Python tree refers to the tag, allowing for modifications to Tk
    should they be necessary.

Switching to the most recent Tk release is a good idea, anyway, so b) is
preferred.
