Thanks. That's kind of disappointing...
Sure -- but it is also inline with how technologies have always
been rolled out. CoreData was Tiger+, for example. CoreAnimation
is Leopard+.
I was hoping that GC support would involve just a single flag or
something that would exist in the binary and would be ignored by
previous OS releases. That's the impression I got when GC was "pre-
announced" in Xcode 2...
That is how it works in Leopard [in a simplistic fashion], but the
generated code makes calls that do not exist in Tiger.
