[vtkusers] GCC 4.0.0

[François Bertel]

I don't think it is related to the gcc version. Did you include 
vtkUnstructuredGrid.h? If not, there is no way for gcc to find the 
relationship between a vtkDataObject and a vtkUnstructuredGrid, that is 
vtkUnstructuredGrid is a subclass of vtkDataObject. It does not complain 
about knowing nothing about vtkUnstructuredGrid because there might be a 
forward class declaration of vtkUnstructuredGrid somewhere else.
