Comment (by cjones051073):

 Above commits implement the changes for clang16-18

 clang17 now works OK for me, tested fine on MAcOSX10.11 for a few of the
 previously failing ports.

 clang18 seems to have another issue, e.g. mesa on MacOSX10.11

 so for now clang18 is still not allowed on older OSes.
