[BUG] Example code has compilation error in cython tutorial - Primes with C++
**Describe the bug**

I encountered a bug when following [cython tutorial - Primes with C++](https://cython.readthedocs.io/en/latest/src/tutorial/cython_tutorial.html#primes-with-c)

I used the [code](https://github.com/cython/cython/blob/master/docs/examples/tutorial/cython_tutorial/primes_cpp.py) which is presented in the tutorial, and named it to `primes_vec.py`. I used the `setup.py` (shown below) to compile it, but it failed with error.

```python
from setuptools import setup
from Cython.Build import cythonize

setup(
    ext_modules = cythonize(
        [
            'primes_vec.py',
        ],
        annotate=True,
    ),
)
```

```shell
python setup.py build_ext --inplace
Compiling primes_vec.py because it changed.
