Does not build when installed via Python3.7+

[Jayjader]

Attempting to install orderedset via pip in python3.7 and 3.8 fails with error containing message error: command 'gcc' failed with exit status 1.

Steps to reproduce (lines prefixed by $ contain the commands):

$ python3.7 -m venv venv37
$ ./venv37/bin/pip install orderedset

A quick search online yields these similar issues in other projects: 1 2, and in particular this comment seems to contain a possible fix.

The root idea appears to be that the cached C source files generated by Cython were not regenerated for release 2.0.2's enabling of use with python3.7 & 3.8, and thus contain symbols present in python3.6 but removed in 3.7 onwards. These cached files furthermore seem to be used when Cython is absent from the virtualenv. If Cython is already present, the C source files are generated on the spot, and seem to be compatible with the python version present (3.7 and 3.8).

Output in my terminal:

$ ./venv37/bin/pip install cython

The apparent quick fix is to regenerate and republish the C source files to pypi.

Additionally, the comment I linked above mentions adding cython to the setup_requires argument to setup (sourcing this stackoverflow answer). However, I am unsure if this will work given discussion on other issues found on github, notably this comment.

For completeness's sake, installing with python3.8 fails with the same behavior, whereas using python3.6 succeeds.

Personal environment:

• ArchLinux running kernel 5.5.5-arch1-1
• Python version 3.7.6

I reproduce the bug on Debian testing (error when installing orderedset only, fixed by installing cython before installing orderedset).

Versions used:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux bullseye/sid

I reproduced the bug when using the basic python:3.7 docker image (Debian GNU/Linux 10 (buster))

❯ docker run -it python:3.7 bash
root@e4465e1c01e0:/# pip install orderedset

Thanks, was sure I had regenerated the C file, but apparently not. 2.0.3 out.
