Thanks!  I committed everything except these two changes:

While it's reasonable to accept changes that will help ObjC frontend
code coexist with C++ frontend code, I think it's premature to
start making explicit cross-references like these.  Objective-C++
hasn't even been officially proposed as a new frontend for FSF GCC,
and so we can't know whether these particular includes will be the
right way to implement it.
