Seems to fail because of a format error, possibly in lou_translateString.c. How can I find the exact error?

It's OK, we can fix that while merging. As long as the 4 other builds pass, it's fine.

I would have changed "warning: pass1Only mode has been deprecated" to "warning: pass1Only mode is not supported anymore". And I also notice now that lou_translateString.c didn't have such a warning, maybe it should be added.

To be honest I'm not very happy with the way we have set up the travis test to check the quality of the source code. I've reopened #438.

@BueVest Thanks for fixing the warnings.

The formatting issues are not real errors, you shouldn't care too much about it. The check is just there to remind the person who does the merge to fix the formatting first.

You could do it yourself by running make format-sources and committing the changes. You need to have clang-format installed for this. However the issue is that apparently newer versions of clang-format behave slightly different.

Is there anything else I need to do here before we merge?
Turns out that Clang is not that easy to install on Ubuntu on Windows, so I probably can't fix the formating, at least not just now.

@BueVest No everything is fine, it will be included in 3.5. Thanks!
