<span style='display:block; white-space:pre;color:#404040;'> clang-17: disable verbose_abort in availability
</span><span style='display:block; white-space:pre;color:#404040;'>
</span><span style='display:block; white-space:pre;color:#404040;'> when availability tests are disabled (macports-libcxx, darwin 10)
</span><span style='display:block; white-space:pre;color:#404040;'> a fallback set of defines are used in
</span><span style='display:block; white-space:pre;color:#404040;'>
</span><span style='display:block; white-space:pre;color:#404040;'> include/c++/v1/__availability
</span><span style='display:block; white-space:pre;color:#404040;'>
</span><span style='display:block; white-space:pre;color:#404040;'> however, the fallback defaults to indicating that libcxx contains
</span><span style='display:block; white-space:pre;color:#404040;'> a verbose_abort function. This is currently always false for MacPorts
</span><span style='display:block; white-space:pre;color:#404040;'> uses, and so link errors occur.
</span><span style='display:block; white-space:pre;color:#404040;'>
</span><span style='display:block; white-space:pre;color:#404040;'> disable this by default, so a fallback pathway is used
</span><span style='display:block; white-space:pre;color:#404040;'>
</span><span style='display:block; white-space:pre;color:#404040;'> closes: https://trac.macports.org/ticket/68640
</span><span style='display:block; white-space:pre;color:#404040;'>
</span><span style='display:block; white-space:pre;color:#404040;'> this has no effect on the normal functionality of this header,
</span><span style='display:block; white-space:pre;color:#404040;'> as the __APPLE__ pathway is used otherwise.
