What basename(3) does with the argument depends on _GNU_SOURCE and inclusion of libgen.h. This is problematic on Musl (1.2.5) as reported. We want the GNU semantics that does not modify the argument. Common way to make it portable is to add own helper. This is now implemented in path_basename() that does not use the libc provided basename but preserves the semantics. The path_dirname() is just for parity, otherwise same as dirname().
