thanks. i was interested further in comparison so i took this file:

https://python.org/ftp/python/3.6.8/python-3.6.8-embed-amd64.zip

then use tar for fair comparison:

    tar -a -c -f python-3.6.8-embed-amd64.tar.xz python-3.6.8-embed-amd64

result:

    $ wc -c python-3.6.8-embed-amd64.tar.xz
    5630160 python-3.6.8-embed-amd64.tar.xz

compare this with cygwin version:

    $ wc -c python36-3.6.8-1.tar.xz
    5746648 python36-3.6.8-1.tar.xz

and that doesnt include the other packages i previously discussed. so it almost
makes more sense to not even use the cygwin version?
