 Replying to [comment:12 mcs]:
 > I can reproduce the problem with my own ESR60-based build. I started
 with the 8.0a9 tag, changed app.update.url to point to a test server that
 I control, and replaced the udater's MAR signing certificates with one
 that Kathy and I generated. So — minimal changes.

 > Kathy and I think we should merge the workaround that we developed (see
 comment:7) until a proper fix inside mingw-w64 is available. If we agree
 on that approach, I will test the workaround in an ESR60-based build and
 make it available in a git repo.

 Sounds good to me.

 > Is there someone we can ask about the underlying mingw-w64 bug? I am
 concerned about spending too much time on this ticket at the expense of
 other tasks (which is not to say that working updates are not important).

 Yes, we should try to get some help. There are three venues I currently
 can think of. We can mail Jacek and ask, ask on the mingw-w64 mailing
 list, and ask folks on #mingw-w64 in OFTC's network. I'll start with
 asking Jacek and might ask around in #mingw-w64.
