----------------------------------------------------------------

The default, LLVM-based, C++ compiler shipped by Apple does not come with a C++ support library.
Instead, Apple  folds (almost) all C++ support in _libc\+\+_, an implementation of the C\+\+
Standard library, leaving only a small layer outside, in the form of _libc\+\+abi_, in order
to facilitate the portability of the C\+\+ Standard Library.

Pathscale produces and released libcxxrt, based on _libc\+\+abi_, which adds the missing C\+\+
support to _libc\+\+abi_, effectively replacing gcc's _libsupc\+\+_.

> The library does not configure properly and build on Mac OS X 10.7.x (Lion), with the
stock compiler (LLVM, using a gcc front-end). The main issue is the lack of a C++ support
library.
