Hello, I was doing my random web browsing when I stumbled on an issue with source code with MSVC++ 2005 Express, and I was searching for a solution. I think I found one, but it hasn't been maintained for years from what I can gather. Since you guys do have winelib for the purpose of building Win32 source code, I thought that I could suggest that the people that do maintain Winelib could take over this project and import it into Wine's git repository. The project is called the Open Foundation Classes, and it aims to be "100% compatible with the MFC and will be improved in various ways. All not compatible parts are signed with a prefix." The link for OFC is: https://sourceforge.net/projects/ofc/
It has a CVS (blech) repository which is obviously linked in the SF project page.
