Which raises the question about how the IEEE 754 gets implemented in POV-Ray's
source code, and if a user can test for -0 through SDL.

I actually just watched:

yesterday (it was in the sidebar when watching yesbird's animation), and they
went over some interesting points, and was also wondering if we could implement
something like this in POV-Ray SDL, and source, and if you'd find it useful or
are already using it in povr.
