* the same feature macro, such errors are hard to detect. Platform
* macros (e.g., _WIN32 or __GNUC__) are a little better, but can
* easily lead to very messy code. It's best to limit yourself
* to only the most generic programming techniques in the test harness
* and thus avoid conditionals altogether. Where that's not possible,
* try to minimize conditionals by grouping platform-specific tests in
* one place (e.g., test_acl_freebsd) or by adding new assert()
* functions (e.g., assertMakeHardlink()) to cover up platform
* differences. Platform-specific coding in libarchive_test is often
* a symptom that some capability is missing from libarchive itself.
