I noticed that "python36" requires "binutils".
This is needed for ctypes.util.find_library(). FWIW, on Linux, not
only binutils is used, but also gcc.
Further, I noticed this dependency chain:
python36 > libuuid-devel > pkg-config > libglib2.0_0
Until 3.7, the uuid stdlib module loads libuuid via ctypes, hence the
dependency. In 3.7, there is a compiled binding, and so the -devel
dependency was dropped. Also, pkgconf will soon be providing and
replacing pkg-config, which will cause the glib2.0 dependency to be
dropped.
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?
