94  * configuration errors.  The classic example of this is omitting a
95  * configure check.  If libarchive and libarchive_test both look for
96  * the same feature macro, such errors are hard to detect.  Platform
97  * macros (e.g., _WIN32 or __GNUC__) are a little better, but can
98  * easily lead to very messy code.  It's best to limit yourself
99  * to only the most generic programming techniques in the test harness
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.
