This should actually help to recognize flipped normals. I probably 
wouldn't have had this brilliant idea...

But unfortunately, the diagnosis does not yet cure the disease and, as 
far as I know, POV does not offer an option for this. With Blender, 
however, you can display normals and there are several tools to invert them.

Since you are working with Blender anyway, you should repair the mesh 
there and then export it to POV.
