----------------------------------------------------------------
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 porting 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\+\+_.
