Is this change correct? The compiler won't synthesize these ivars when they're
declared as weak, since the file isn't compiled with ARC. I'd be fine with
changing it back, since cleaning up ivars is secondary.

I'm confused by your statement. There is an explicit @synthetize for these
property in the .mm, why would you think those would not work?

Ok. for MRR assign is correct and weak is incorrect (as the instance variables
were markes unsafe_unretained). Your change is correct.
