On September 30, I built (jhbuild) gtk+3 and gtkmm3 on MAC Sierra with 
only one problem.  I think that the OS was still 10.12.0 at that time.  
I used Xcode 8.0 on a virgin installation of Sierra. The only problem I 
had was with cups which was fixed with the solution given at 
https://mail.gnome.org/archives/commits-list/2016-June/msg03579.html 
(edited .../gtk/gtk+-3.20/configure.ac as per the instructions on that 
page (changed gt to lt)).

If you cannot resolve the problem you have, let me know and I can run 
another install to see if the current OS is any different for me.
