I guess the issue here is about what decisions one might be trying to
make based upon seeing:

OS == :unix

It might be best for hybrid's like cygwin, gnv, and so on if we
reported something unambigous, e.g.

OS => :hybrid
IMPL => :cygwin, :gnv, etc...

At least this way you can plan what you're going to do if you're not
on a straightforward platform.

e.g.

if OS == :unix
  # do unix
else if OS == :hybrid && IMPL == :cygwin
  # handle Cygwin case

or

if OS == :unix || ( OS == :hybrid && IMPL == :cygwin )
  # we don't care

I'm tempted to wonder about "hybrid-unix" but think that might be
getting too complicated.  In all likelyhood there aren't that many
combinations that would need to be given special treatment.
