True, but I would like to do this only for those tests that need it.
That is, only for those tests that use the test fixture that provides
the my_system() functionality.  So if I have

  struct system_fixture {
    int run (const char *cmd) { return my_system (cmd); }
  };

  BOOST_FIXTURE_TEST_CASE (test_false, system_fixture)
  {
    BOOST_CHECK_EQUAL (EXIT_FAILURE, run ("false"));
  }

  BOOST_AUTO_TEST_CASE (test_true)
  {
    BOOST_CHECK_EQUAL (EXIT_SUCCESS, my_system ("true"));
  }

I don't want system error caught for test_false but I do want them still
caught for test_true as that is not supposed to cause any.

The example is a bit contrived and overly simplistic but I hope you see
what I'm thinking of.

Thanks in advance,
