 * pointed-to strings to be in a particular section.
 *
 * Anyway, a test consists of:
 * 1. Expected glob_match result: '1' or '0'.
 * 2. Pattern to match: null-terminated string
 * 3. String to match against: null-terminated string
 *
 * The list of tests is terminated with a final '\0' instead of
 * a glob_match result character.
