I doubt spreading option code over separate files will help consistency.

I suspect the true root of the problem is having (too many) OS-specific
options in the first place.  What about parsing options the same
everywhere, calling out to OS-specific functions to do the actual work?
Let them fail with "can't do this on this OS".
