[vtkusers] Help upgrading

[Gavin Tabor]

Dear all,

I've been trying to migrate some CFD visualisation codes from 2.4 to 3.2
(latest version of VTK) and have hit a snag. 
As far as I can make out, the same header file -
vtkMarchingSquaresCases.h
is getting included twice, and a "typedef struct" instruction is getting
screwed up. I don't understand why this is happening, or what I can do
to
stop it happening. (I also don't understand why it wasn't happening
before
- the header files in 2.4 and 3.2 are the same). 

Any suggestions would be appreciated.
