TypeScript: Signature for '???' duplicated

• Create WinJS Application for Windows 8
• Add Windows 8 javascript library to project
• Add ddts phonegap typescript definition library from https://github.com/borisyankov/DefinitelyTyped
• Add script.ts file to project
• enter

code:

///<reference path="phonegap.d.ts" />

var x = 1;

      

        
        
        
      

    

Now if you "compile" the script.ts file in VS I get the following error

C:/Program Files (x86)/Microsoft SDKs/TypeScript/lib.d.ts(4551,4): 
Signature for 'clearWatch' is duplicated

      

        
        
        
      

    

In my VS 2012 I also have the following extension installed (which may be related to the problem, but not sure)

• TypeScript
• Web Essentials
