100 * and thus avoid conditionals altogether. Where that's not possible,
101 * try to minimize conditionals by grouping platform-specific tests in
102 * one place (e.g., test_acl_freebsd) or by adding new assert()
103 * functions (e.g., assertMakeHardlink()) to cover up platform
104 * differences. Platform-specific coding in libarchive_test is often
105 * a symptom that some capability is missing from libarchive itself.
