/* Tester needs to verify that an error message is written for each */
/* invocation of strerror and perror. She should also check that the */
/* output from perror is in this form: User's message, colon, blank, and */
/* then the standard error message. Finally, the tester needs to ensure */
/* that when errno is set to EDOM and ERANGE, the error message written */
