Yes indeed. Thanks for catching and correcting this.

Well, as that would cover my past needs (where on certain architectures we
had switch from -O2 to a lower optimisation setting or g77 would die;
obviously a g77 bug and now mostly (?) fixed) so I'd say yes.
Not hugely pressing as the current system has worked, but I would at certain
points in the past have like to have this available.
