Hmm.  My attempted workaround pollutes stderr on some setups, thus
causing this failure, even though I had not encountered it on any of
the platforms I tested before the release.  I'll fix it for m4 1.4.20,
but in the meantime, you can ignore the failure and use the build (the
bug is in the testsuite, not in the built binary).

My bad; I missed the '-9' instead of '9' in that suggested command.
