I looked at the diff. It is true clang-14 gives a warning while clang-15 gives an error, but they both fail afterwards at link time (the functions in question do not exist by default, they are in <bsd/string.h> and -lbsd). So in this case the functions are not implicitly declared, they are simply missing. Also if the functions did exist, `check_symbol_exists` has an include file, so they would both succeed.
