Needs a custom copy constructor and copy assignment operator to avoid double
frees. If no copying is needed, we can just declare them private.

Done

   operator BSTR();
 private:
   BSTR value;
+  BString(const BString&);
+  BString& operator=(const BString&);
 };
 
 std::wstring DllDir();
 std::wstring UserSettingsFileUrl();
 std::wstring FileUrl(const std::wstring& url);
