I'm not sure I see the problem.  What does '-qlanglvl' do that
'-qlanglvl=extc89' does not?  In other words, what breaks because of
autoconf's choice?

OK, I can agree that it looks a little weird.  But does it still behave as
though extc99 had been specified alone when both occur on the command
line, and -qlanglvl=extc99 was specified last?

The testsuite.log shows no failures, so either the testsuite is missing a
test, or autoconf is working just fine for your platform.
