I have found a patch for make 3.73, to remove the bug with LFN's.
This patch works for me ok in both cases, when LFN is set to y
or n.

Some comments about the changes:

1) I use the variable '__opendir_flags', to tell 'readdir' not to
   convert the filenames to lower case, when LFN is enabled, with
   the help of the very good macro '_USE_LFN' in the 'init_dir'
   function.

2) The function 'dosify' must not modify the filename, if LFN is
   enabled.
