-- Small change to smb_discard_netbios_frames() for better debugging
-  and profiling.
-
-- Integrated Tygre's proof-of-concept changes for much improved 16 bit
-  Unicode drawer and file name support. Thank you very much!
-  
-  These changes allow for file and drawer names to be used which smbfs
-  previously could not adapt for the Amiga (they would be omitted from
-  drawer listings).
-
-  Please note that this feature requires more memory since every such
-  file or drawer name will have to be stored for reference. This memory
-  will not be released until smbfs has shut down, even if the files or
-  drawers on the server's side, corresponding to what smbfs remembers,
-  have already been deleted or renamed. Also, if you rename or delete
-  such files or drawers through smbfs, the memory allocated for them
-  is not yet released (this will have to follow in another release).
-
-  In order to make these file and drawer names accessible, smbfs will
-  make it appear as if they had different names. These new names are
-  "aliases" which only smbfs uses and likely will not match the
-  originals.
