Cygwin would be nice, esp. to produce releases, but I’m not sure if Appveyor provides such an
image yet. They are just a small Russian company, not so high-powered as Travis in Berlin.

First I wanted to get MSVC passing, then I wanted to switch over to mingw, which is supported,
and smoke with win32 and win64.

Eventually add a cygwin setup in a local cache, for much easier testing, but I haven’t done
this yet in other projects. I have to look around.
I gave up on cygwin locally some years ago, as I could switch fully to darwin/linux and do
not maintain my windows machines anymore.
Only eventually I’ll have to do that, most likely to debug libsigsegv on win64. This was the
latest blocker when I left.

Yes. I explicitly wanted to catch some errors there, on such old platforms.
Apparently I found some :)
