Yes, that's it. And after some stupid problems -- I then used
\newcounter instead of \newcount and forgot about \releasecounter --
I even got it working in my other documents and pdfpages, too.
I am happy now!

I added one more indirection, so that one does not have to
distinguish between \AddLabel and \StepLabel:

\def\@AddLabel{\global\let\SetLabel\WriteLabel\AtShipout{\KillLabel}}
\def\KillLabel{\global\let\SetLabel\relax}
\def\AddLabel{%
  \ifthenelse{\boolean{instepwise@TP}}
    {\ifthenelse{\boolean{firstactivation}}{\@AddLabel}{}}
    {\@AddLabel}}

Now \AddLabel is working within and outside of \stepwise.

Thank you very much for your help. I appreciate it.

Ciao
Andreas
