What do you mean by "very recently"?  The vtkType stuff has been there
for 2 years almost unchanged. AFAICT this should have always been a problem.

A temporary solution is to follow your proposal to consider long long
before long when looking for a 64-bit integer type.  Let's go with that
for now.

The real problem is that the vtkTypeInt64Array class is defined
differently depending on the architecture.  Instead of generating the
class it should make the selection at preprocessing time.  Some kind of
hack will have to be put in to the Tcl wrappers to make the same
selection at preprocessing time when compiling the wrappers.
