My old xlc does not show that option, it is unfortunately version
specific.
The currently compatible option to turn it off would be -qnoansialias
So we can use:
xlc -qnoansialias
The default cc options are: -qlanglvl=extended -qnoro -qnoroconst
So I guess we could also use (but above is imho clearer/better):
cc -qro -qroconst -qlanglvl=extc89
