I think there's a few which have C interfaces. I didn't check nor am I familiar enough with Cygwin, are no-arch dirs being used for libs? I am pretty sure DLLs were built. Can someone have multi-lib/multi-arch Pythons installed in Cygwin? I've only ever used a single arch myself.

Thanks. Subbed.

I am using the repos I found here: The versions I found here are the same versions I already had installed for Python 3.7. Here's the explicit package list:
python38-asn1crypto           0.24.0-1                        OK
python38-crypto               2.6.1-2                         OK
python38-cryptography         2.6.1-1                         OK
python38-lockfile             0.12.2-2                        OK
python38-openssl              19.0.0-1                        OK
python38-pyasn1               0.4.5-1                         OK
python38-pyasn1-modules       0.2.4-1                         OK

I built what's currently in the repo (with one small minor change to a single package) b/c I noticed what's going on in python-wheel cygclass. This also leads me to ask another question: must I have both Python 3.7 and Python 3.8 installed for all/any packages?

It would seem that one must make sure python-openssl 1.2.3 build and work (test suite passes) for both Python 3.7 and Python 3.8 based on this setup. Is this always true?

Also, from my inspection of the cygport's cygclasses, the "default" is to not build Python 3.6 flavored packages, only Python 3.7 and Python 3.8. Have I got that right?

I also didn't spot any testsuite passes, but I didn't check the PyPy sources if testsuites are distributed or not.

I figured it best to get what's already in the repo build for 3.8, and then consider package updates later.
