[Insight-users] 64-bit and mhd long int output (watershed 'labelled' image)

[Atwood, Robert C]

The good news is that the results on a Intel em64t (SUSE 9.1 gnu/Linux
distib) for my use of the watershed appear good and somewhat faster than
on the 32 bit machine. The bad news is that I only get half the output.
I traced the problem to 'magic numbers' for the data element size
defined as constants in metaTypes.h shown below. 

I am not sure how it should be fixed in keeping with overall ITK program
style, I would use a preprocessor directive for a quick fix assuming
that CMAKE can set a macro by probing the system information Is there
already a macro created for this purpose?

or perhaps it is better in the long run to use a sizeof() -- then I
don't think it can be const and cannot be set in the header file?

Also, I could not find the itk::MetaImageIO member object m_MetaImage in
the Doxygen list of all members, though it appears in the header file as
displayed by Doxygen.
