IPhone C ++ / Objective-C exceptions

Question

Does anyone know the implications of enabling C ++ exception handling in Xcode applications for the iPhone? By default it is disabled.

Are C ++ and Objective-C exceptions the same or can there be C ++ exceptions only for C ++ code and vice versa?

thank
