What about:

$ sftp localhost
Connecting to localhost...
sftp> symlink 'C:\Windows' bar
sftp> cd bar
sftp> ls *exe
Alcmtr.exe                FramePkg.exe              HideWin.exe

IsUninst.exe              MicCal.exe                RTHDCPL.exe

RTLCPL.exe                RtlUpd.exe                SkyTel.exe

SoundMan.exe              alcwzrd.exe               explorer.exe

hh.exe                    regedit.exe               twunk_16.exe

twunk_32.exe              winhelp.exe               winhlp32.exe


I don't have my sftp chrooted, but I don't know any reason why the above
wouldn't work on a Cygwin chrooted system.
