Hi!

There are a lot of Mac:s still used where the last supported OS version is
10.6.8. It would be a nice touch to support them, at least as long as all
we need to come up with is a good set of preprocessor tests to exclude
code. Of course, should we need to put a lot of effort into maintaining
support, I too would vote for dropping them (after all, there are fairly
modern versions of Emacs available for them).
