I do indeed now seem to have admin access on Appveyor. Thanks for
that. I guess I should therefore say that if anyone needs help with
Appveyor stuff, feel free to ping me and save Zach from getting all
the work :-)

When working via github on the web (which I was) rather than on a
local checkout where I can search, putting it in a subdiretory is a
bit less discoverable (made worse because there's nothing about the
name ".github" that suggests it would have Appveyor files in it :-))
I'd prefer it at the top level - but not enough to submit a PR for
that at the moment, so I'm fine with it staying where it is.

Nice catch. I'd agree, it's probably not worth having both
(particularly as, if Victor says, we have buildbots for the one
Appveyor doesn't cover - but even if we don't I think VSTS has it

I presume you're suggesting keeping 2017 is so that we don't have
stray 2015-built artifacts in the cache, which makes sense to me, and
I have a mild preference for keeping the latest compiler, as that's
likely the one that people will find easier to get. But 2015 is
presumably the version the official 3.6 builds are made with, so
there's an argument for keeping that one (although if we do that I
guess we need to find a *different* way of fixing the cached artifact

tl; dr; I'm inclined to agree with you that just using VS2017 on
Appveyor is the simplest option.
