NOTE:
This formula provides components that were removed from XCode in the 4.2
release. There is no reason to install this formula if you are using a
version of XCode prior to 4.2.
This formula contains compilers built from Apple's GCC sources, build
5666.3, available from:
https://opensource.apple.com/tarballs/gcc
All compilers have a `-4.2` suffix. A GFortran compiler is also included.
