Hello,
I have an error (about symlinks it seems) that i have never met in years: Cannot change mode.
Apart from this message (and return code != 0), the ’tar extract’ is ok.

% uname -a
CYGWIN_NT-10.0-17763 {edited} 3.5.0-0.295.g3bee68248fc8.x86_64 2023-05-01 17:58 UTC x86_64 Cygwin
% cd /tmp; rm -rf mytest mytest.tar
% mkdir mytest
% ln -s b mytest/a
% /bin/tar cf /tmp/mytest.tar mytest
% /bin/tar tvf /tmp/mytest.tar
drwxr-xr-x {edited}/{edited} 0 2023-05-24 13:12 mytest/
lrwxrwxrwx {edited}/{edited} 0 2023-05-24 13:12 mytest/a -> b
% rm -rf mytest
% /bin/tar xf /tmp/mytest.tar
/bin/tar: mytest/a: Cannot change mode to rwxr-xr-x: Not a directory
/bin/tar: Exiting with failure status due to previous errors
% echo $status
2
%

/tmp is under ntfs filesystem, all packages are up to date (e.g. /bin/tar --version is 1.34).

Regards,

Denis Excoffier.
