The patch is ok with me (but see below).  BTW, the idea of having an
'errexit' clean `tests/defs' sounds good to me, indipendently from the
issue at hand.  But I won't go as far as asking for a separate patch ;-)

IMVHO, we should just reject a shell with such an untrustworthy `set -e'
behaviour.  My pending patch "Testsuite: use $SHELL to run tests which
are shell scripts":
 <http://lists.gnu.org/archive/html/automake-patches/2011-01/msg00033.html>
might be a first step in ensuring that the automake tesuite is run with
a "sane" shell (if that's available).

That said, ATM I'd just apply your patch, it's definitely worth to have
if it removes 60-70 spurious test failures!
