Hadrian

[Simon Peyton Jones]

Ah.  I hadn't even tried the stage2 compiler (in the stage1/ directory).  Yes, that works.  But perhaps a script to get to it would be helpful, otherwise invoking stage1 will look entirely different to invoking stage2.  Not a bid deal, I grant you!

|  Does the stage2 compiler which is found in `stage1/bin/ghc` not work for
|  you? I thought the issue was that the stage1 compiler doesn't work.
