4 tmpd=`mktemp -d ${TMPDIR:-/tmp}/err-names-XXXXXX`
IIRC, constructs like:
${TMPDIR:-/tmp}
can be made more portable:
${TMPDIR-/tmp}
by removing the colon before the dash.
Not true. Use of : is portable to all shells that support functions, which is pretty much every shell out there today (including Solaris /bin/sh). Autoconf has already proved this point.
