Running Emacs with LFN enabled requires that the files which are part
of the Emacs distribution are stored on disk with long names.  Is that
possible with DOSLFN and LFNDOS?  If not, you cannot have what you
want, I think.

If one of these drivers does support long file names on disk, then you
need to install Emacs (unpack the zip files) again with long file
names turned on and with an unzip program that supports long file
names.

Please be warned that long file names support in Emacs 19.34 was
tested on Windows 9X, so it might not work well on plain DOS with LFN
support from another kind of driver.
