+Getting a Modern Host C++ Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This section mostly applies to Linux and BSDs. On Mac OS X, you should have
+a sufficiently modern Xcode, or you will likely need to upgrade until you do.
+On Windows, just use Visual Studio 2012 as the host compiler, it is explicitly
+supported and widely available.
+
+However, on Linux and BSDs there are some notable distributions which have
+extremely old versions of GCC. These steps attempt to help you upgrade you
+compiler even on such a system. However, if at all possible, we encourage you
+to use a recent version of a distribution with a modern system compiler that
+meets these requirements. Note that it is tempting to to install a prior
+version of Clang and libc++ to be the host compiler, however libc++ was not
+well tested or set up to build on Linux until relatively recently. As
+a consequence, this guide suggests just using libstdc++ and a modern GCC as the
+initial host in a bootstrap, and then using Clang (and potentially libc++).
+
+The first step is to get a recent GCC toolchain installed. The most common
+distribution on which users have struggled with the version requirements is
+Ubuntu Precise, 12.04 LTS. For this distribution, one easy option is to install
+the `toolchain testing PPA
+<https://launchpad.net/~ubuntu-toolchain-r/+archive/test>` and use it to
+install a modern GCC. There is a really nice discussions of this on the `ask
+ubuntu stack exchange
+<http://askubuntu.com/questions/271388/how-to-install-gcc-4-8-in-ubuntu-12-04-from-the-terminal>`.
+However, not all users can use PPAs and there are many other distros, so it may
+be necessory (or just useful, if you're here you *are* doing compiler
+development after all) to build and install GCC from source. It is also quite
+easy to do these days.
+
+Easy steps for installing GCC 4.8.2:
+
+.. code-block:: console
+
+  wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2
+  tar -xvjf gcc-4.8.2.tar.bz2
+  cd gcc-4.8.2
+  ./contrib/download_prerequisites
+  cd ..
+  mkdir gcc-4.8.2-build
+  cd gcc-4.8.2-build
+  %PWD/../gcc-4.8.2/configure --prefix=$HOME/toolchains --enable-languages=c,c++
+  make -j$(nproc)
+  make install
+
+For more details, check out the `excellent GCC wiki entry
+<http://gcc.gnu.org/wiki/InstallingGCC>`, where I got most of this information
+from.
+
+Once you have a GCC toolchain, use it as your host compiler. Things should
+generally "just work". You may need to pass a special linker flag,
+``-Wl,-rpath,$HOME/toolchains/lib`` or some variant thereof to get things to
+find the libstdc++ DSO in this toolchain.
+
+When you build Clang, you will need to give *it* access to modern C++11
+standard library in order to use it as your new host in part of a bootstrap.
+There are two easy ways to do this, either build (and install) libc++ along
+with Clang and then use it with the ``-stdlib=libc++`` compile and link flag,
+or install Clang into the same prefix (``$HOME/toolchains`` above) as GCC.
+Clang will look within its own prefix for libstdc++ and use it if found. You
+can also add an explicit prefix for Clang to look in for a GCC toolchain with
+the ``--gcc-toolchain=/opt/my/gcc/prefix`` flag, passing it to both compile and
+link commands when using your just-built-Clang to bootstrap.
