Hi:
Recently checking the PKGCONFIG for emacs in arch linux 
https://github.com/archlinux/svntogit-packages/tree/packages/emacs/trunk

I see that they needed to add 3 patches to emacs 27 to avoid some issues.
I am wondering if this fixes 

1. are needed in general2. if (1.) are these changes or equivalent already in the emacs 27 branch?
