May I suggest that sharutils 4.3.77 and 4.3.78 are not put in directories
named "4.3.77" and "REL-4.3.78", then? The current layout is a little
bit misleading.

Ok, here is a patch that maybe you can accept:

This patch tries not to break the MSDOS stuff. For Unix, there is no
need to unlink the file (the tmpfile function already does this), not
to mention we don't even know the name of the file, so we have to
change the error message a little bit to not reference name_buffer,
since it does not have any useful value.
