I believe including this in the (yet to be created) gcc-7/porting_to.html,
would be great.

Historically the porting_to.html documents have mostly covered C and 
C++, since that is the source language of the majority of packages in 
a GNU/Linux distribution that GCC touches.  Adding more focus on
Fortran users as well feels like a good idea, though.

(If you want to go ahead, but prefer the page to be created first,
let me know, and I'll take care.)
