[vtkusers] vtkToolkits.h in vtk 4.0

Hi,
    i've some warnings i can't understand :

In file included from
/giref/logiciels/vtk4.0/include/vtkXOpenGLRenderWindow.h:57,
                  from vtkQtRenderWindow.h:44,

gmake[1]: Entering directory
`/home/cmpgiref/compilation_MEFPP_egcs/COMPILE_AUTO/InterfaceQtVTK/src/interface/VTK'

they seem to come from vtkToolkits.h who has no "#ifndef  ...  #endif"
around the "#define VTK_USE_OGLR" so that the macro is redefined
frequently whereas there is no "#ifndef  ...  #endif" around the body of
".h" . I don't understand how to remove these warnings as my boss
forbids me to change "vtkToolkits.h". Which compilation flag do i have
to set on?

thx
