GHC: The Glasgow Haskell Compiler.

The Glasgow Haskell Compiler is a robust, fully-featured, optimising compiler for the functional programming language Haskell 98 (http://www.haskell.org). GHC compiles Haskell to either native code or C. It implements numerous experimental language extensions to Haskell, including concurrency, a foreign language interface, several type-system extensions, exceptions, and so on. GHC comes with a generational garbage collector, a space and time profiler, and a comprehensive set of libraries.

This package provides the 7.10.x release series, which is the last version that can bootstrap with 7.6.x. It will probably be removed once we make a separate package for GHC 8.0.x and get enough bootstrap kits for it.
