Comment (by cjones051073):

 macports-clang-17 is not broken all OSes. it works just fine on
 macOS15(arm64) at least, I was able to build python312 and odin just fine
 there using it. whatever the issue is here, if it is an issue with the
 compiler its limited to older OSes.


 I have no ability to do any testing on other platforms than the above, so
 won't be investigating this one myself.
