The SeCreateSymbolicLinkPrivilege privilege is filtered by User Account
Control (UAC).  If your account is a member of the "Administrators"
group, then the process needs to be run with your elevated credentials
in order to make use of the SeCreateSymbolicLinkPrivilege privilege.

The "Administrator" account always runs in an elevated state and
accounts that are not members of the "Administrators" group do not have
their security tokens filtered by UAC.

Does Cygwin permit binaries to be built with manifests?  If so,
winln.exe could include an embedded manifest that indicates that
elevated status is required.  The user would then be prompted by UAC
whenever the command is used.
