It was in trying to get my Windows Dev environment back up and running again that got me frustrated and gave me an excuse to wander off doing other things... IIRC, there is a build issue with the Py2 bindings in that branch on Windows, but I never got far enough to check it out.

Hmm, okay, just tried again ... same problem. Here is some more output:

I tried with both the x86-64 and the x86 builds of Python 3.7.4 ...
same result. Weird. I'm continuing to investigate.

In other news, building the swig-py3 branch (after sync-merge from
trunk) with Python 2.7.16 (and swig 3.0.12) was successful.
Running the testsuite gives some failures though:
