commit 4b0ef83dc5e4acf06e21a71412b9274d80456408

    Allow test-suites to work with GHC < 7.0.
    
    Due to several problems with older versions of GHC and Cabal,
    some extensions have to be switched unconditionaly in test-suites
    to allow GHC < 7.0 to work.
    
    The reason is
    * GHC < 7.0 cannot handle conditional LANGUAGE pragmas and therefore
      the extensions have to be specified in cabal file.
    * GHC = 7.0 with bundled Cabal cannot handle conditionals in
      test-suites and so we cannot enable the extensions conditionally.
    
    When testing with GHC < 7.0 is no longer necessary, the extensions
    in test-suites can be removed.
