The cs-list error should be easy to fix ... and I have some memory of this bug 
(or a similar one) already being fixed. As the sources you are using don't 
match the default branch, please type the following.

        octave:1> system (sprintf ("grep -n \"^\" %s | head -n 400 | tail -n 
50", which ("print")))

(there's probably a better way to do that) In any event, I get the result below.

351:            props(end+1).h = h(n);
352:            props(end).name = "fontname";
353:            props(end).value = {get(h(n), "fontname")};
354:          endif
355:        endif
356:        if (ishandle (h(n)))
357:          if (! isempty (opts.fontsize))
358:            props(end+1).h = h(n);
359:            props(end).name = "fontsize";
360:            props(end).value = {get(h(n), "fontsize")};
361:          endif
362:        endif
363:      endfor
364:      if (! isempty (opts.font))
365:        set (h(ishandle(h)), "fontname", opts.font);
366:      endif
367:      if (! isempty (opts.fontsize))
368:        if (ischar (opts.fontsize))
369:          fontsize = str2double (opts.fontsize);
370:        else
371:          fontsize = opts.fontsize;
372:        endif
373:        set (h(ishandle(h)), "fontsize", fontsize);
374:      endif
375:    endif
376:
377:    ## call the graphcis toolkit print script
378:    switch (get (opts.figure, "__graphics_toolkit__"))
379:    case "gnuplot"
380:      opts = __gnuplot_print__ (opts);
381:    otherwise
382:      opts = __fltk_print__ (opts);
383:    endswitch

389:        if (ishandle (props(n).h))
390:          set (props(n).h, props(n).name, props(n).value{1});
391:        endif
392:      endfor
393:    endif
394:
395:    ## Unlink temporary files
396:    for n = 1:numel(opts.unlink)
397:      [status, output] = unlink (opts.unlink{n});
398:      if (status != 0)
399:        warning ("print.m: %s, '%s'", output, opts.unlink{n});
