I don't think you need to apologize, in fact your post stopped me from
posting similarly.

The clue here is, does it only work for this type of OS?  If yes then it
isn't portable anyway but should it be?  And does it only work on this
type of OS because of an issue that could change as a result of a fix.
Cygwin has always been and will always be a work in progress.  The rule
of thumb "does it work on Linux" should be applied to all that you do
with Cygwin.  If it only works on Cygwin and not on Linux then the
chances are, something will change.
