The builds I am responsible for include it because someone reported an issue and was persistent and helpful enough that I fixed it for them.

That said, until MinGW agrees on a stable branch/version/fork, there seems to be a good chance that the shipped lib won't work for some people. If this is what's happened here, I see it as a good enough reason to stop shipping the lib and to add instructions on generating it instead (the gendef/dlltool dance).

Agreed. If shipping it helps, then great. If it's going to cause bug reports, let's go back to the status quo of not having it. The instructions for generating it were in the old distutils docs, now removed in the cleanup / redirection to packaging.python.org. I'm inclined to just leave it undocumented - the people who need it know how to do it or can find it, whereas documenting the process implies a level of support that we're not yet really able to provide.

Let's wait to see what the OP comes back with before making a final decision. I see a few questions:

  1. Does using distutils work (as opposed to the quoted manual compile steps)?
  2. Does using whatever process he used in the past to generate libpythonXY.a result in a working version?

https://docs.python.org/2.7/install/index.html#gnu-c-cygwin-mingw suggests using pexports rather than gendef. I don't know if that could produce a different result, but I can't see how... It also implicitly assumes you're using dlltool from the toolchain you'll be building with rather than using -m. Again, I can't see why that would affect the results.

It's been so long since the last Python release that I didn't remember that I had to make the lib file.

I made libpython35.a like I did for the others and it's all working now. All the tests pass. :-)
