X11.h #defines 'Status' and 'Failed' and 'Succeeded' which conflicts with the enum in DetailedPromise. So rename the 'Status' enum in DetailedPromise so that the build works on Linux. Some of my changes here caused DetailedPromise to be included in more places that it was before, which caused build failures on Linux.
