 This is a wrong patch.
 libc++ does not provide `__cxa_demangle` (and `cxxabi.h`);
 it's [http://libcxxabi.llvm.org/ libc++abi] that provides them.
 I withdraw the patch.

 In Mac OS X, to build libc++, libc++abi is needed
 (libc++abi is dynamically linked to libc++ and its symbols are re-
 exported).
 So using libc++ in Mac OS X implies that the functionality of libc++abi is
 also available.
 {{{
 #if defined(__GLIBCXX__) || defined(__GLIBCPP__) ||
 (defined(_LIBCPP_VERSION) && defined(__APPLE__))
 }}}
 can detect this environment (and I locally use this code).

 Sorry for the noise.
