  Added files:

  Log:
  Change the type of System.Cmd.rawSystem:
  
    rawSystem :: FilePath -> [String] -> IO ExitCode
  
  and implement it properly on both Windows & Unix.  The intended
  meaning is that the program is executed with *exactly* these
  arguments.
  
  We now re-use this rawSystem in the compiler itself (using it directly
  from the library if __GLASGOW_HASKELL__ >= 601).
  
  The previous implementation of SysTools.runSomething was broken on
  4.08, because Posix.executeFile was broken.  However, implementing the
  new rawSystem on 4.08 is tricky, because it uses the FFI marshalling
  libraries which weren't present on 4.08.  Hence, bootstrapping from
  4.08 is now not possible (it was already not possible on Windows).  It
  could be made possible by importing enough FFI marshalling support,
  but I won't bother doing that unless/until it is needed.
