Bug ID: 49729
           Summary: Test the macOS build
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

Running the tests on macOS requires being able to run macOS in a LibVirt VM
which is tricky. But just testing the macOS Wine build can be achieved in the
Linux VM and is thus a much easier goal to achieve and may be enough to make
sure that patches don't break the macOS build.

The following Docker containers provide a blueprint for how to set up such an
environment:

* OSXCross provides the cross-compilation tools
  https://github.com/tpoechtrager/osxcross

* PhoenicisOrg provides an OSXCross-based container for building macOS Wine
