If you have a clash with anything in w32tk.e, you can safely remove the
one in w32tk.e. This file just contains aliases for things that win32lib
used to be using but no longer does.

Win32lib does not get along nicely with tk_*.e files. I could put namespace
qualifiers on all the win32lib references but when one is looking at 35,000
lines of code, the task is a bit daunting. 

If at all possible, can eucom avoid tk_*.e or using namespace qualifiers?

Not a clever idea, really. It is a *lot* safer to use euinc. I think that
one of the entries in euinc can be a 'relative' path to the current folder.

  set EUINC=.\include;
