8  Test case for assertion #1 of the sigaction system call that shows
9  sigaction (when used with a non-null act pointer) changes the action
10  for a signal.
11
12  Steps:
13  1. Initialize a global variable to indicate the signal
14     handler has not been called. (A signal handler of the
15     prototype "void func(int signo);" will set the global
16     variable to indicate otherwise.
17  2. Use sigaction to setup a signal handler for SIGUSR2
18  3. Raise SIGUSR2.
19  4. Verify the global indicates the signal was called.
