[Paraview] Error parsing header while compiling plugin

[David Doria]

I am trying to compile a plugin. It is telling me:

syntax error
*** SYNTAX ERROR found in parsing the header file vtkPTXReader.h
before line 55 ***

This is the file it is complaining about:
http://www.rpi.edu/~doriad/Paraview_List/PTX/vtkPTXReader.h

That header works fine when compiling non-plugin executables. Is there
something in there that is not allowed for plugins?

Thanks,

David
