There are two loops which look like this: https://github.com/Kitware/ITK/blob/master/Modules/Core/Common/include/itkImageAlgorithm.hxx#L148
for ( unsigned int i = movingDirection; i + 1 < _RegionType::ImageDimension; ++i ) The use of the +1 there with the loop control variable is a little odd, but it was done to avoid a -1, and signed/unsigned interaction. I'd be curious of changing that made this warning go away, in exchanged for the signed/unsigned comparison warning.
