[vtkusers] Error compilling with mingw

[Wolfgang]

Hello,

I'm quite new to VTK but I want tu use the python (2.5) bindings. During 
compillation with mingw32 I get the following error:

[ 13%] Building CXX object 
Common/CMakeFiles/vtkCommonPythonD.dir/vtkPythonUtil.
obj
C:\VTK\Common\vtkPythonUtil.cxx: In function `PyObject* 
PyVTKClassMetaType_GetAt
tr(PyTypeObject*, char*)':
C:\VTK\Common\vtkPythonUtil.cxx:771: error: invalid conversion from 
`const char*
' to `char*'
mingw32-make[2]: ***

Error 1
mingw32-make[1]: *** [Common/CMakeFiles/vtkCommonPythonD.dir/all] Error 2
mingw32-make: *** [all] Error 2

Any Ideas?
