We are down to 6 warnings on several linux gcc systems. The warnings all come from this class: itkVectorFuzzyConnectednessImageFilter.txx We are down to 12 on another system, with most of the warnings coming from here: IO/itkVOLImageIO.h and here IO/itkVTKImageIO.cxx Can the authors of the classes please take a look at fixing the warnings. Thanks. -Bill
