--- Comment #1 from Stian Low wineryyyyy@gmail.com --- Previous efforts involving Cygwin were mixed between: 1. Getting Wine to work in Cygwin 2. Getting Cygwin to work in Wine
This issue is about 2. Getting Cygwin to work in Wine. https://gitlab.winehq.org/wine/wine/-/wikis/Cygwin-and-More#cygwin-in-wine
The primary reason to get Cygwin working in Wine is to get Emacs running in Wine as well as it does in Windows which works about as well as Linux allowing for it to be used almost exclusively between both systems in a very consistent manner.
Wine dev efforts may benefit from having Emacs hacking environment available for additional debugging capabilities.
