New submission from Sander Vrijders:
I am writing C90 compliant code and am wrapping my C headers with SWIG, which
includes python3.6m/pyport.h. I've told my compiler to report all warnings as

```
/usr/include/python3.6m/pyport.h:40:1:
Sander Vrijders added the comment:
Okay, a bit conflicted about the following though. The changelog refers to
PEP7. This document indeed states that Python versions greater than or equal to
3.6 use C89 with several select C99 features, such as C++-style line comments.
