cygwin vs docker

[Igor Kostenko]

Unfortunately I'm unable to reply to the previous thread. Posting
workaround which working for me - locations and names emulating cinst
cygwin:
md c:\tools\cygwin
cd c:\tools\cygwin
curl -Sso cygwinsetup.exe https://cygwin.com/setup-x86_64
start /wait cygwinsetup -q --root C:\tools\cygwin -P
dos2unix,make,perl,python27,python38,rsync,libxml2,pbzip2,mc -X --site
http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2020/05/31/142136/

Version from May 31st is ok, version from June 1st breaking docker.
