Looks good, Staffan! I tried creating an x64 project and it works 

A couple of questions:

* Do we have to allow duplicates file names due to the closed src 
( 238-244)?
* Are the Eclipse autogenerated methods in 
needed? Should they be included?
* When I bild an x64 project in Visual Studio I get to choose between 
Win32 and x64 in the platform drop down list. The Win32 platform does 
not build (expected behaviour). Could that be removed from the drop 
down? This is not important it is easy to select x64, so no show stopper.

And minor thing. Copyright year should be 2011 for all files.

Thanks for fixing this!
