I get that -- I really do.  The suggestion to use a few conditionals
that look at the which OS you're on does not involve continued tweaking.
Once you have the right file, it works everywhere (for which you have
provided suitable cases) using the exact same file. It's just that
different parts get executed on different platforms.  It's not as
elegant as achieving an arrangement with no conditionals, but it's
practical and flexible. I've done it for years myself!
