wither the Platform

[Thomas Miedema]

>From the downloads <https://www.haskell.org/ghc/download_ghc_7_8_4> page on
the GHC homepage:

Version 7.8.4 (released December 23rd 2014)

Stop!

For most users, we recommend installing the Haskell Platform
<http://hackage.haskell.org/platform/> instead of GHC. The current Haskell
Platform release includes a recent GHC release as well as some other tools
(such as cabal), and a larger set of libraries that are known to work
together.
