          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.
