At the end of observer.c, we have a bit of code that used in the gdb.gdb/observer.exp testcase. Since the variables and functions are declared static, the compiler simply optimizes these out. The attached patch fixes this. Objections? Mark Index: ChangeLog from Mark Kettenis * observer.c (observer_test_first_observer, observer_test_second_observer, observer_test_third_observer): Don't define as `static'. (observer_test_first_notification_function, observer_test_second_notification_function, observer_test_third_notification_function): Likewise.
