It would appear the autoconf 2.60 pretty much insists on using -qlanglvl=ansi
in this case.

I think this will work around it.  You will need to run "autoreconf" from
autoconf-2.60 to rebuild the configure.  If you don't have it handy, you
can download a prebuilt one here:

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
