Hello,
'down-nailed'  my problem (see below) to next few lines
in  file  ~/src/modules.c (around line 533). I included 
the #ifdef and #endif lines - and voila, cvs behaves as
expected.

#ifdef HAVE_MAJOR_HACK
      /* XXX - XXX - MAJOR HACK - DO NOT SHIP - this needs to
         be !pipeout, but we don't know that here yet */
      if (!run_module_prog)
         goto do_special;
#endif
      dir =3D where ? where : (mwhere ? mwhere : mname);
      /* XXX - think about making null repositories at each dir here
         instead of just at the bottom */
      make_directories (dir);
      if ( CVS_CHDIR (dir) < 0)
      {
         error (0, errno, "cannot chdir to %s", dir);
         spec_opt =3D NULL;
         err++;
         goto do_special;
      }

Two questions remain:
(a) after all, what does  the  above 'XXX - XXX' comment
    mean and where will cvs fail now?
(b) my naive assumption about an  (ampersand) module was, 
    that a module is something  like an abbreviation for
    a (possible)  large  list  of  arguments to cvs, e.g. 
    writing the ampersand module
      am &mod1 &mod 
    and executing 
      $cvs co am
    is exactly equivalent with
      $ cvs co mod1 mod2
    or, in  other word, my assumption was that an argument
    identified as 'module' gets expanded by its definition
    but the result of this  expansion is evaluated then as 
    if I had typed it manually on the commandline.
    But this is  not the case: my assumption is that there
    are two evaluation procedures, one for modules and one
    for 'files' and my question is just: why?
    
Bye,
Wolfi.
