Please describe exactly how does LFN support fails in Emacs.  It was 
tested under Win95 and in general works (although some bugs might still 
be there).

Are you running Emacs under Win95?

That's a typo, right?  It's LFN, not LNF.

Do you set LFN=y from the DOS prompt or from DJGPP.ENV?

That is normal behavior.  The LFN flag is only set at runtime, AFTER the 
program's startup, when the first file-oriented operation is done.

I don't think that's the right direction to look for the cause of the 
problem.  Please post the details of the case where LFN isn't supported.
