Current behavior
When compiling using webpack, in angular rc7 core libraries there are a couple of warnings.

Expected behavior
I guess no warnings... :-)

Reproduction of the problem
Install a bare project, the simplest you like using webpack with the Angular2 rc7 revision and you will get the warnings.

Please tell us about your environment:
All the last versions of Angular2 rc7, typings, ts and webpack related dependencies. All of them on the latest versions npm has.

• Angular version:
  2.0.0-rc.7
