OK, but the new test he added (marked '+' below):

   { ac_out=`sed -n '/\${datarootdir}/p' "$tmp/out"`; test -n "$ac_out"; } &&
+  { ac_out=`sed -n '/^[[       ]]*datarootdir[[        ]]*:*=/p' "$tmp/out"`; 
test -z "$ac_out"; } &&

looks pretty portable to me.  If it breaks, then I'd expect the
existing sed-based test to break too.

(But if you're coming up with something better, never mind.  :-)
