[issue29215] pyport.h uses non C90-style comment

[Sander Vrijders]

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 errors. Compilation fails with the following error:

```
/usr/include/python3.6m/pyport.h:40:1: error: C++ style comments are not allowed in ISO C90
 // long long is required. Ensure HAVE_LONG_LONG is defined for compatibility.
```

I believe the comment was added by the patch of a previous bug (see https://hg.python.org/cpython/rev/4745d801cae2). The solution would be to change this comment to a C90 comment.
