I understand that this is not as interesting anymore since gyp is gone and  
Windows is a smaller platform than it used to be, but for the record, I've  
kept working on it in between other things and the total gain is about 7  
minutes, which is better than the 25% estimate.

This is in chromium land with the patch in http://pastebin.com/90vx4sep  
and the script in http://pastebin.com/WmzGY8zs. Both are pre-blink so they  
should look familiar, though they apply to gyp files which are gone.  
Neither have been cleaned up so they are a bit embarrassing but if someone  
wants to keep working on this in WebKit they might be a good starting  

To do in that case:

* Port to the new build system for Windows.

* Test compile a lot of platform and verify gains in Windows.

* Integrate the idltopath.pm map generator into the build system.

* Apply.
