Yes, you are right. To meet the requirements of POSIX, I am using the
following in my scripts:

  tmpdir=${TMPDIR-${TEMP-${TMP-/tmp}}}/$progname.$$

So, the variables TMPDIR, TEMP and TMP are used (priority descending).

Well, many people use $$ for temporary *filenames* in directories that
have world-write permissions. This is a securiry whole (e.g. symlink
attacks). Reinhard is using the $$-name for creating a *directory* and
aborts if this fails. This is a reliable way to prevent security wholes.

One suggestion: I would write
  (umask 077; mkdir "${TMPDIR}") || die "Can't mkdir ${TMPDIR}"
to make the code even safer (the newly created directory will only be
accissible to the user; independed of the user's default umask).

Yes, I think that many traditional UNIX systems don't have it.
