--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Patch approved at https://gcc.gnu.org/ml/fortran/2019-02/msg00116.html.

As a general comment, there is no point to attach change logs to bugzilla: 
it is enough to add them when submitting the patches to the mailing lists.

I also think there is no need to file a PR for such trivialities.
