Then it is not possible for a file name in that directory to exceed 255
bytes (in the native encoding). By definition.
So unless the maths VLC performs below the fpathconf() call, is wrong, VLC
has no bug there.
(Whether readdir_r() is useful is a different question, but if you want to
remove it, please check it is OK and please remove vlc_readdir() too.)
