Still waiting on a review for this patch. Comments/concerns from all
are welcome.

The patch looks fine to me.

OK for trunk, and thanks for the patch!

@Gerald: Will a gcc-7/changes.html file be generated?  If so, we should
document this new flag (and others...)

Yes, please!  Segher beat me to it today, sorry for the delay, and
thanks for thinking of our release notes.

Let me know if you need any help.

I would be happy to document my new flags (I have added several) in
upcoming release notes or applicable documents - however I do not know
where or how.

I tried to summarize how to checkout and contribute to the web pages
at https://gcc.gnu.org/about.html and will be happy to answer any 
questions and improve that page as well.

Once you have checked out wwwdocs (the name of the web module), 
you'll find the release notes for GCC 7, mostly empty for now, at
  htdocs/gcc-7/changes.html

There is a Fortran section there, which you can start filling. :-)

Any way I can help, let me know.
