Re: Should we split the project into two branches?

[Derek Fawcus]

I don't know about the level of changes needed in GCC, or about the
possibility of using an objC preprocessor, but it was possible to
build and deploy ARC using (including __weak references) code to 10.6.8.

As I recall one had to build against the 10.7 SDK, and then add an
extra package for the __weak support.

So in theory one could do something similar regarding the libobjc1 code.
