thanks for the suggestion. 
Because I have never patched wine before and I am relatively new to linux and
github, I just wanted to be sure what I'm doing is correct.

git clone git://source.winehq.org/git/wine.git
cd wine
git-apply patch #the patch you posted.
git commit -a

and then I'm a bit lost from here.
Is there a way to build from the local git using pacman or yay?
