  * Rejig the #ifdeffery
  Put __hscore_?_OK and __hscore_S_I?USR in the C inside
  #ifdef __GLASGOW_HASKELL__ to match the foreign imports in the Haskell
  code.
  
  Don't check the constants are defined before defining the C functions,
  as we assume that the functions exist in the Haskell code anyway.
