It also means that C++11's std::exception_ptr will correctly be able to shift your exceptions around between threads.  It's also what Clang happens to enforce, so you'll need to add a bunch of new checking if you don't want to do it. :)

That indeed sounds desirable…

… while this does not. I'd like to not depend on anything C++ related at all, so that I could even compile with a GCC that only has --enable-languages=c,objc.

Maybe I'll check in configure if $OBJC supports C++ and add some #ifdefs. But then, still, I'd rather not have references to mangled symbols that contain the GNUstep namespace.
