That will work in this case too. (The cygport script runs autogen.sh.) If you choose instead to try to build from the source tarball without even looking at the cygport file, you get what you paid for. In the case of the Cygwin package, there is an alternative: You can follow the instructions at https://cygwin.com/faq.html#faq.programming.building-cygwin for building Cygwin from source. This explicitly mentions running autogen.sh. This only has to be done once, after first cloning Cygwin's git repo. After that, everything is updated as needed by the Makefile. Prior to running autogen.sh, there's no Makefile and no configure script. So I guess autogen.sh accomplishes something useful. Finally, I'd like to mention that it's extremely common for autotools-based packages to have an autogen script like Cygwin's (sometimes called bootstrap or bootstrap.sh). There's nothing surprising about this. Ken
