I've tried all this above with a corresponding r.basin.bat, r.wf.bat and
r.ipso.bat in C:\Program Files\GRASS 6.5.SVN\bin (the python-scripts
r.basin.py, r.wf.py, r.ipso.py are in C:\Program Files\GRASS
6.5.SVN\scripts).

but I'm not sure the content of r.basin.bat should

@"%GRASS_PYTHON%" "%GISBASE%\scripts\r.basin.py" %*
or
@"%GRASS_PYTHON%" "%GISBASE%/scripts/r.basin.py" %*

my little python-testscript is:
testpython.py
#!/usr/bin/env python
import sys
print sys.prefix
print
print sys.path
print
print sys.version

any mixing of the different python versions within the grass-session?
