in the wrapper script, we have to munge single-quote characters heavily. 
 It's possible I missed something -- here's the relevant code:

    --trace=* | -t?* )
       traces="$traces '"`echo "$optarg" | sed "s/'/'\\\\\\\\''/g"`"'"
       shift ;;
    --trace | -t )
       test $# = 1 && eval "$exit_missing_arg"
       shift
       traces="$traces '"`echo "$1" | sed "s/'/'\\\\\\\\''/g"`"'"
       shift ;;

and later:

if [ "x$traces" != "x" ] ; then
  opt_traces="--trace=$traces"
fi

A few quick tests (editing the wrapper script to "echo" instead of 
"exec") show that something is not right...but I can't track it down 
right now -- and trace is fairly infrequently used.

For now, either track down the problem and send in a patch :-) or just 
set PATH=/usr/autotool/devel/bin:${PATH} ...
