As the error message indicates, it seems that somewhere before the 
inclusion of that .inc file, your scene - or some other .inc file it 
happens to include - has already defined that very same identifier as a 
macro.

POV-Ray hates you when you try re-defining macro identifiers as 
something else, unless you #undef that macro first.
