Hmm. Not sure what's going on here. The function openw is just:

(defun $openw (file)
   (open
      (l-string file)
      :direction :output
      :if-exists :supersede
      :if-does-not-exist :create))

So if the file exists, it should be silently clobbered.

It is possible the definition of openw in your installation is different.
You might try the above definition instead, if so.

The behavior you reported might also be a bug in the Lisp implementation.
What Lisp version are you using? (And what Maxima version?)
