 issue with the OSGeo4W-wingrass.

 I'm getting closer now to the issue:

 testcase:

 - download
 https://wingrass.fsv.cvut.cz/grass72/x86_64/WinGRASS-7.2.svn-r69794-61
 -Setup-x86_64.exe

 - install the standalone WinGRASS-7.2.svn-r69794-61

 - start it normally from the windowa menue by ''"C:\Program Files\GRASS
 GIS 7.2.svn\grass72svn.bat" -gui''

 => everything works fine without any numpy error in winGRASS startup!

 next steps:

 - copy env.bat and grass72svn.bat from the ''C:\Program Files\GRASS GIS
 7.2.svn\'' installation to a folder, e.g. D:\temp\testgrasspython

 - in D:\temp\testgrasspython\grass72svn.bat, ''set GISBASE=C:\Program
 Files\GRASS GIS 7.2.svn'' points to the standalone installation

 - change in D:\temp\testgrasspython\env.bat that the python stuff points
 to the OSGeo4W-python:

 {{{
 set GRASS_PYTHON=C:\OSGeo4W64\bin\python.exe
 set PYTHONHOME=C:\OSGeo4W64\apps\Python27
 }}}

 and now you get in the standalone installation (while pointing to the
 OSGeo4W-python stuff) the same numpy error in startup like in the OSGeo4W-
 winGRASS.

 conclusion:

 there must be a difference between the ''python stuff of the standalone-
 winGRASS-build environment'' and the ''OSGeo4W-provided python stuff''!!
