Or maybe this would be better, by creating a subsidiary process to drain
off the pipe (at which point, you have to be careful about how $? is
tested).  Also untested, but shorter than Bruno's proposal, and does not
have to worry about shell signal handling (which is somewhat difficult to
do portably):

test `echo hi | { ./conftest$ac_exeext; echo $?; cat > /dev/null; }` = 1

Don't work too hard, make some time for fun as well!
