requirements, which should fix issues relating to using vector types in
Objective-C objects.
+- The option to build a separate libobjcxx has been removed. The runtime will
+ now depend on the C++ standard library implementation if no useable C++
+ runtime is available. Note that C++ exception interworking does not work
+ because LLVM's libc++abi (shipped by Apple) does not provide GNU-compatible
+ hooks and so Objective-C++ exception support will be automatically disabled
+ on this platform. Any other platforms shipping libc++abi should consider
+ either GNU libsupc++ or libcxxrt as an alternative.
