title: Duplicate identifier/duplicate string index signature with code on a mounted drive
body: <p>My typescript project resides in c:\data.
  c:\data maps to f: via a mounted drive :</p>

  <p>I use Visual Studio 2015, Typescript Tools 2.0.5 with npm Typescript@2.1.5</p>
  
  <p>Typescript in visual studio somehow picks up both/two paths pointing to the same  d.ts typing files, e.g. C:\data\xpsdev\trunk\web\workforce.mvc\node_modules\@types\jquery\index.d.ts 
  AND 
  F:\xpsdev\trunk\web\workforce.mvc\node_modules\@types\jquery\index.d.ts</p>
  
  <p>resulting in duplicate identifier/signature errors in the error list..</p>

  <p>How can I avoid Visual studio not to take into account both paths ???</p>
  
  <p>Excluding "f:\xpsdev" in tsconfig did not work...</p>
