Hello Ricardo,
I triggered this build error while working in an older codebase that uses C89 due to legacy support reasons. Indeed - will focus on submitting C11 compatible fixes even when working on older codebases.
Thanks for the review Ricardo,

Hi Desdes
How did you trigger this build warning? I believe we use C11
