There now is a patch in addition to [4] that people seeking to fix the
described issue may be interested in.

Dirk Meyer of FreeBSD brought my attention to a broken case with munpack
that was shipped broken with the original 1.6 upstream tarball but may
have been fixed by the removal of O_EXCL applied by earlier attempts to
fix the insecure tempfile handling (as with FreeBSD).

So with O_EXCL back in (or still in place), patch [5] can be used to
repair munpack.
