clang trunk if -fobjc-runtime-1.7 is specified and provides significantly better interoperability with foreign exceptions. Note: Most of the exception tests will not pass with gcc or clang < 3.3. They test things that are impossible to implement quite correctly with the GCC-compatible exception ABI. Also updated the release notes to reflect recent improvements.
