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 SIGUSR1
18   3. Raise SIGUSR1.
19   4. Verify the global indicates the signal was called.
