The rtti unit can be compiled for 3.2.2, it will miss some functionality, 
but it will still be available. The only thing it really relies upon from
trunk is the actual extended rtti info, so people will get limited info.

vcl-compat indeed relies on some trunk compiler features (the JSON stuff), 
but probably not as many as you seem to suppose. Some IFDEFs will get us 
a long way. I developed most of it, so I'm pretty sure of this.

I'm not saying that everything will be easy, but it's definitely doable.

Michael.
