Why both of them have to be updated? There are far more consumers
of Autoconf than of Autotest. I suggest to remove the limitation
from AT_CHECK documentation only. Ultrix is rare these days, and
people willing to run the generated testsuite there will have to use
a working shell.
What about the following patch?
