I couldn't figure out how a POSIX filename passed to a Cygwin application running on the Windows system may become longer than NAME_MAX=1020 bytes if the maximum filename length in NTFS is 255 UTF-16 symbols (i.e. 1020 bytes for the biggest 4 byte UTF-8 code unit)? 
What causes the ENAMETOOLONG error? In the most of POSIX functions ENAMETOOLONG is returned if the length of a component of a pathname is longer than {NAME_MAX} or the length of a pathname exceeds {PATH_MAX}. On NTFS there is no files with pathname component longer than 1020 bytes and the length of the full pathname is limited by the Unicode API (32767 chars * 4 byte = 128KiB).
