• This function succeeds when the RENAME_NOREPLACE flag is specified and the source and destination are the same file, on some platforms: Cygwin 3.4.6.
• renameat2 (AT_FDCWD, "file", AT_FDCWD, "new/" ...) succeeds instead of failing and setting errno to ENOTDIR, on some platforms: GNU/Hurd with glibc 2.41.
• renameat2 (ATFDCWD, "dir", AT_FDCWD, "new/" ...) fails with errno set to ENOENT, on some platforms: GNU/Hurd with glibc 2.42.
• renameat2 (ATFDCWD, "dir/", AT_FDCWD, "new" ...) fails with errno set to ENOTDIR, on some platforms: GNU/Hurd with glibc 2.42.

The renameatu module addresses some of these portability issues.
