The cythonize `ddtrace/profiling/collector/stack.pyx` cannot be compiled.

I have tried to add Cython directive 'language_level' to 3 in `setup.py` but the compilation still failed.

```python
    use_scm_version=True,
    setup_requires=["setuptools_scm", "cython"],
    ext_modules=cythonize(
        [

For information with ddtrace 0.36.1 is working fine (the issue start with 0.37.0)

Discussion:
Hi! Thanks for the report. Excuse me in advance as I barely know anything about Windows. :)

Do you know if you've headers (and maybe DLLs?) available to build Python extensions in general? The fact that it seems to be unable to link symbols makes me think that's not the case.
I can confirm I am having the same issue trying to install on Win10, even with all the Win Python build tools installed.  Something changed with the packaging of ddtrace that made it stop installing on Windows correctly.
Hi, I have re-installed python with full option to be sure that doesn't came from a missing library or DLL, I still have the issue. My colleague (on windows also) had the same issue too. Do you need more information?
Hi @cyface, @opiot 

Yeah looks like the Windows installation was broken when we started requiring C-extensions. We're going to look into the install issues as well as adding Windows to our CI.
