/usr/share/doc/cygwin-doc/html/cygwin-ug-net/using.html#pathnames-symlinks
/usr/share/doc/cygwin-doc/html/cygwin-ug-net/using-cygwinenv.html
https://wiki.samba.org/index.php/UNIX_Extensions#Minshall.2BFrench_symlinks

Because of potential differences from user customization of symbolic link types
thru the CYGWIN environment variable winsymlinks:{lnk,native,nativestrict} and
file system type dependencies, ranging from lack of any symlink support on
CIFS/Samba to real symlinks on NFS, symlinks are created in Cygwin package
postinstall scripts to honour customizations or work around limitations.
