Wine makefile meant for older version of wine no longer works due to missing header

Hi. I’m trying to make Wineasio for Fedora 31. Doing this under Fedora 29, the only extra package I can recall installing was the wine-devel package.

The makefile for the wineasio download is not working on my Fedora 31 install because I’m missing wine/unicode.h

I’m assuming this error can be resolved by installing another package? If so, what am I missing?

EDIT: It appears this header was removed in a wine update a few months back. When I completed this process on my laptop with Fedora 29, this update had not yet taken place. Anyone with familiarity with this issue, please advise on the best course of action to work around this problem.
