Can someone explain what the iso_rcsg.inc functions do?  I am not sure 
what "rounded" means.

It's a tool to make iso_surfaces shapes whose edges are round rather than sharp like
those of normal 
primitives like a box.

The macros in iso_rcsg.inc generate distance functions for the shapes 
they represent while the normal macros in iso_csg.inc just ensure the 
function is zero at the shape surface.

Note there are a lot of shapes that have a distance function macro in 
iso_csg.inc (like sphere, torus, triangle) so they don't need a separate 
one in iso_rcsg.inc.

Thanks Christoph.  Could you suggest a test that would show up the 
difference?

Well the file includes macros for both IC_Box and IC_Round_Box

I was posting some test screens at the time I was working on it:
