Sorry, no.
The actual type should only be returned in dirent.d_type if the info is
available at very low cost. This is not the case for Cygwin symbolic links.
If DT_UNKNOWN is returned, lstat() must be called if type info is required.
Quote from Linux man page readdir(3):
"All applications must properly handle a return of DT_UNKNOWN."
