  * Change how we find the host/build/target platforms
  Rather than using the autoconf built-in stuff and mangling it, we
  now just ask the bootstrapping compiler what platform we are on.
  
  When doing a port of GHC, you need to specify the platform you are
  porting to.
  
  The minimum version of GHC required is now 6.8.

    M ./configure.ac -619 +178
    M ./mk/project.mk.in -6
