  * Fixes for cross-compiling to a different word size
  Ignore-this: f5f1769ae247a3eb735662ea90926f96
  This patch eliminates a couple of places where we were assuming that
  the host word size is the same as the target word size.
  
  Also a little refactoring: Constants now exports the types TargetInt
  and TargetWord corresponding to the Int/Word type on the target
  platform, and I moved the definitions of tARGET_INT_MAX and friends
  from Literal to Constants.
  
  Thanks to Barney Stratford <barney_stratford at fastmail.fm> for helping
  track down the problem and fix it.  We now know that GHC can
  successfully cross-compile from 32-bit to 64-bit.

    M ./compiler/basicTypes/Literal.lhs -26 +1
    M ./compiler/prelude/PrelRules.lhs -3 +5
    M ./includes/HaskellConstants.hs +22
