12		The build on Cygwin takes very long because various overheads compared to a build on Linux. On GH Actions there is a time limit of 6 hours per job. Therefore I have split the build into several jobs ("stages"), some of which run in parallel. The linked build https://github.com/mkoeppe/sage/actions/runs/285244461 is the `cygwin-standard` build, which means that I install binary packages from the Cygwin distribution first and then start the build of Sage.
