It may work in some cases, but it didn't even compile against the cvs
VTK. The politically correct action would be to set it to IdType in
the parser and to let VTK itself decide if that should be an int or
not. My suspicion is still that the Octaviz parser is producing code
that is working most of the time but that some obscure undocumented
feature or bug of the VTK shipped with Debian let it slip by during
compilation.

This involves making quite a few modifications to the Octaviz parser,
in order to make it work with later versions of the VTK bison and flex
grammar files. I haven't worked on this for the past couple of weeks,
and the next few weeks involve preparing finals for my students and
lots of bureaucracy. I still plan, however, to dust off my
undergraduate notes on parsers and context free grammars and see how I
can synch Octaviz's parser with the better 64-bit aware grammar. ;-)

Of course, I have been slow in the past complying with this sort of
thing, so feel free to do it yourself if you get impatient with me.
