  Modified files:
    src/compiler98       Rename.hs 
  Log:
  Fix an obscure bug in the scoping rules for local where clauses.
  Previously, the following definition
      f x = x where x = True
  produced the error message
      ======  Errors when renaming:
      Redefinition of Identifier x at 5:5
  but apparently it is legal in H'98 to shadow pattern bindings in this way.
