The issue is due to ISO C23 declaration of bsearch, memchr, strchr, strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr, which now returns a pointer to a const-qualified type when the input argument is a pointer to a const-qualified type [2]. I would like to thanks Emanuele Rocca for doing the archive rebuild on a fast arm64 server.
