Since the question is only for 32-bit builds, does this even m
But even if so do we WANT to now be supporting 4 Windows platforms?

and then, what about sse3, etc???
Longer term, more platforms (particularly more platforms that really only
differ by some compiler flags) shouldn’t be a very big deal, because my

It should be fine either way as long as the CPU can handle the particular

You could, I suppose, patch your custom Python to *not* treat wheels
built for cp35-none-win32 (or cp35-none-win_amd64, as appropriate) as
compatible with that build (that requires a patch to the tag matching
code in pip). You then wouldn't be able to use any binary wheels on
PyPI, which is a bit h
