nope, not fixed yet.


i.cluster/main.c has:
    if ((reportfile = parm.report_file->answer) == NULL)
        report = fopen("/dev/null", "w");


there is no /dev/null on Windows, so it fails to open the file.

work-around: specify reportfile=something.txt


others that need fixing:
 raster/r.out.mpeg/main.c
 raster/r.topmodel/misc.c
