  * Update lhs-boot files
  
  A consequence of my recent meddling with hs-boot files is that GHC is
  more picky about the correpondence between the hs-boot file and the hs file.
  In particular, you must use the same type synonyms.
  
  This patche fixes up GHC's own hs-boot files to match the restriction.
