I think I actually need that as well :). I would like to be able to 
translate code like this:

#if Windows
     typedef int foo;
#else
     typedef long foo;
#endif

To:

version (Windows)
     alias foo = int;
else
     alias foo = long;

Preferably I would like to do that without having to run the tool on 
different platforms and somehow merge the results.

I know it technically violates the meaning of the source code. I'm just 
trying to automate what a developer would do manually anyway. Doing it 
manually just increases the risk of making mistakes.
