Comment (by mmetz):

 Apparently 0 (zero) and NULL (nodata) got confused in r.external on
 Windows. If I set 0 (zero) to NULL (nodata), I get the exact same
 incorrect results. No idea where and why this confusion in r.external on
 Windows happens.

 Sure, when the fix is there. Professional deadlines, however, cannot wait
 for the real fix.
