Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @GuillaumeGomez (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

Thanks!

I wait for travis' confirmation before r+ it.

Also, can you squash your commits please? If you don't know how to do, take a look here.

[CryZe]

Travis won't confirm, it's broken right now.

[acrrd]

squash done

[GuillaumeGomez]

@acrrd: Travis and buildbot are broken for the moment. Once they're fixed, I'll r+.

[acrrd]

There are some tests that fails, these are tests that check the warning and not the error; with my modifications the label of the warning also changed, is what we want?

(I run make check-stage1, it ends with
test result: ok. 2494 passed; 0 failed; 3 ignored; 0 measured
and only if I scroll a lot up I found
test result: FAILED. 2523 passed; 5 failed; 13 ignored; 0 measured
is there a better way to see the summary of the result of the tests?)

[GuillaumeGomez]

Sure:

make check-stage1-cfail

[acrrd]

Thanks, that will help in avoiding to send PR with tests that do not pass.

What about the tests? I can modify them to the new format also for the warning or I can modify the code the keep the old behavior for the warning.

[GuillaumeGomez]

Just check what the command will return. It'll tell you what you need to update (and how).

[acrrd]

I have the fail also on master so I think my commit is ok

[GuillaumeGomez]

Seems good. Thanks!

@bors: r+ rollup
