It would be nice but I dont expect/want a major overhaul of the header system for you and I with the Mingw and MS_VC work. If one day WINE is going to use some sort of common header/import system that it shares with Mingw/Borland* then I am all for it but atm ReactOS is not contributing much back and I have not had much time to focus on anything so take my vote with a gain of salt.
Thanks Steven
* I think that work is underway for borland or one of the other open compilers to use the win32api/ddk package that the mingw project uses. If this system works and becomes popular it would still be nice to see all of the Open-Win projects be able to work together.
It seems that I'm not the only one having this problem as well. Steven Edwards also wants a way to use the Mingw/W32api package together with Wine in a sane way.
