  Because it is not needed.
  POV-Ray doesn't have a preprocessor like a C compiler has. POV-Ray
directly reads and interprets the SDL code without doing any
preprocessing to it.

  I remember people asking if POV-Ray could just parse but not
render and return an error code (which could be used to check
the validity of the input), but I don't remember anyone asking
if POV-Ray could be used as a "preprocessor".

  It would not be difficult at all to implement, but it would be
rather useless (at least for POV-Ray itself).

  I can think of only one useful use for this feature: To convert
SDL files to a simplified format which is easier to parse by
third-party programs.
