* upstart/tests/test_message.c (test_reader, test_handle_using)
(test_handle); Usual fix for gcc optimiser thinking that fixed
for loops might not be.
* init/tests/test_job.c (test_run_process, test_kill_process):
Likewise.
* init/tests/test_notify.c (test_subscription_find): I still don't
know what a type-punned pointer is, nor why dereferencing such a
thing would break strict-aliasing rules.
* init/tests/test_cfgfile.c (test_read_job): More type-punning.
* util/tests/test_jobs.c (test_start_action): More for-loop action.
* util/tests/test_events.c (test_emit_action): And again.
