I agreee that just converting syntax would not be enough, but it would make OO design in D alot easier and faster. It an idea currently, I was just looking for some input.
Given that there is (by definition) no genuine OO stuff in Wine at the moment, porting Wine (successfully) to an OO language is a task equal to, if not greater than, reimplementing the current state of the codebase from scratch.

Well, being a garbage collected language, it would help with the memory leaks in Wine. Being OOP it could extend the design of the code to make it cleaner and reusable.
The assertions above are opinions, not facts. Also, it requires a full rewrite.

^^ Very important point.
I'm pretty sure that garbage collection on its own does not solve memory leaks. Java is notorious for memory issues; if there's a leak in the engine then no amount of fixking in your code will reduce the memory footprint. Furthermore, if the leak is created by some reference still being valid in the first place (i.e., not being cleaned up by the code, which no doubt is the current case), then any benefits of automated GC would be minimal at best.
Things that cause memory leaks are bad practice, and for a project as large as Wine, I'm not sure relying on a language feature to clean up the loose ends is the best idea.
Also, what benefit could an OO language bring to implementing win32/win64? Are the Microsoft APIs actually suited to object-orientied implementation?

Porting a codebase the size
of Wine will probably take years...
Actually I'm working on a program to convert C code to D code. You can find/replace most instances of code, like unsigned int (C) with uint (D). The import/include files might take some work though.
Just converting the syntax won't help much. It might compile, but it lacks the design changes (such as proper OO) needed to properly exploit a new language. You end up with code with the same problems as the original, but in a language that the programmers are unfamiliar with... (For C++, duplication of functionality in the STL is an example of what often happens if you directly port C code)
Wine (like the Linux kernel) might be a good codebase to test your application on (for your own testing), since it is quite a large, complicated codebase... The chances of having it accepted into Wine is probably quite small... (My guess would be that your chances of being struck by lightning while winning the lottery are about equal...)
http://www.winehq.org/site/docs/winedev-guide/style-notes might give you an idea of some of the things relatively simple patches struggle with to get included...
