(I am not an expert in this area.)

That seems plausible.

I wonder if this belongs in each gcc bl3, but I guess it's only for
gfortran.  I wonder if they each have exactly a dir like this -
basically  I am saying "are you sure that what looks like hoisting this
to a group file is safe"?

I also wonder if you get this error with gcc8 from pkgsrc, and if not
 - what's different
 - given that something is different, why is this fix ok for that
   situation

I don't mean to suggest you are incorrect - just asking questions.
