I finally solved the problem (thanks to single-step lisp debugging in
Emacs):
My shell customization code was conditioned by (eq window-system
'win32).

Well, guess what? in Emacs 19.34 window-system contained "win32" for
the NTEmacs environment, but now in Emacs 21.2 window-system returns
now "w32".

That's what has changed. I wish I could have read it somewhere in the
news without having to go through this debug effort (I am not a lisp
programmmer).

Anyway, now the problem is solved, thank you everybody and I hope that
this tip will help someone.
