Yes, in GCC objc and objc++ are entirely distinct front-ends.  This,  
unfortunately, means that improvements in one do not always get shared  
with the other, and that while objc is almost-unmaintained, objc++ is  
completely unmaintained.

Yes, you need to add objc++ to the list of languages to enable that  
you pass to ./configure.
