Nit: either put a blank line between all of these, or none of them. (I would
prefer this whole file have no blank lines between constants, just a blank
between the switches and paths and one between the paths and the values.

Also please sort these the same way they're sorted in the header file.

Nit: please add a comment saying that the lower-case s can't be changed for
compatibility with older versions, so that people looking at this code in the
future don't "fix" it.

Done.
