I tried setting up a Cygwin Git build on AppVeyor a little while ago,
but the problem I found is that Cygwin builds are slow, particularly if
you want to also run the test suite.  I do the builds for the Cygwin
distribution on my normal PC (so reasonably powerful but definitely not
devoted to the purpose), and doing the build and running the default
tests takes in the region of 8 hours for the 64-bit build and 12 hours
for the 32-bit build.

At the moment, I'm trying to set up automated regular builds on my PC
using BuildBot.  I think that, short of someone donating some fairly
significant resources for Cygwin builds, that's going to be the closest
I'll be able to find for spotting problems early.  It's a project in my
currently limited spare time, though, and not something I've done
before, so it's taking a little while to get going.
