[ITK] Compilation errors

Dear Bill,
Here I have copied a small program which gives the same errors:
#include "Filter_Type_Definitions.h"
int main( int argc, char *argv[])
{
ReaderType::Pointer reader = ReaderType::New();
reader->SetFileName( argv[1] );
reader->Update();
//Apply a median filter
MedianFilterType::Pointer medianfilter = MedianFilterType::New();
GrayscaleImageType::SizeType indexradius;
indexradius[0] = 3; //X radius
indexradius[1] = 3; //Y radius
indexradius[2] = 3; //Z radius
medianfilter->SetRadius( indexradius );
medianfilter->SetInput( input_image );
medianfilter->Update();
}
Now, I have used only itkMedianImageFilter in this example, but in my actual code I am using many more filters. Hence I have kept the file Filter_Type_Definitions.h as it is without deleting the extra filters, in case they are of any help. I have attached the file with this post. I had written many programs before today in which I had included all the headers in the main source code file, and they all compiled without errors. It was only when I kept the headers and typedef's in a separate file that the errors began occurring.
Thanks & Regards,
Ruturaj

Please post a small, complete program that illustrates the problem.
