  If you hack the last line ("exec $testdir/run_all.sh ....") off of a copy of
gcc/testsuite/ada/acats/run_acats, you could probably source it into a shell
to get all the variables set right.  You might also want to hack run_all.sh
(or a copy thereof) to add some "--save-temps" flags in strategic locations.
