[Sparkle] Plan to support garbage collection?

[Mark Munz]

As I understand it, the dual-mode framework will only work on 10.5 or
later. But, you should be able to easily target earlier versions of
the OS with the same source.

I do not believe 10.4 has any official support for dual-mode
frameworks (there was some hint that the compiler support GC, but
that's it). There will likely need to be two targets and two resulting
frameworks:

10.5 and later framework (dual-mode)
10.4 and earlier framework (no-GC)

The source for the non-GC framework should transparently work in
building a 10.4 and earlier framework.
