Hello,
Thank you for all the work on Cygwin! I've been using it to spin up an environment to build the OCaml compiler / toolchain, and it was working great.
However, today, all our CI builds mysteriously started failing - at first, I suspected it was a problem with AppVeyor, but I also failures with VSTS. We use an NPM package (`esy-bash`) to spin up a Cygwin environment, and then use that to build the OCaml toolchain.
The error message we started receiving today is:
