e.g. also in r.watershed
see also https://trac.osgeo.org/grass/ticket/2689
in contrary to #2689, the null file isn't there.

The file in question is

The directory separators are likely wrong. Since it is in libraster it affects several modules.

The bug seems to be related to the recent changes in null data support done in trunk.

I think that it's because r65323 deferred closing the null file (because a compressed null file needs to have the row pointers written out), meaning that the file is still open at the time of the rename() call. This is valid on Unix but not on Windows (although the MSDN documentation neglects to mention this in the description of the EACCESS error for rename()).
So, the order needs to be:
- Write out row pointers
- Close file
- Rename file

#2434 is still valid
#2434 was opened long before any of these changes were made.
right; but there seems to be similar problems with raster:
see e.g. 2434#comment:14
