Thanks.

Do you think it would also make sense to consistently use in C++ 
front-end TYPE_PTR_P instead of TREE_CODE (t) == POINTER_TYPE? It's 
something I noticed a while ago when I cleaned-up predicated related to 
pointers and occurred to me again now that you are doing some of this 
kind of work. If you like I can do this bit.

Thanks,
Paolo.
