Thanks for your reply (however I haven't received it, because you
likely didn't click on "reply all"?).

Do you refer to the recent message [1]?

Regarding cygwin time machine. I can't use it, since cygwin is compiled
for MSYS2. And then it is being run under Wine on GNU/Linux. While
WinXP is still not dead, Wine is definitively not an old OS. It's just
an active project doing WinAPI implementation from scratch according to
documentation. Thus I hope Cygwin developers could talk directly to
Wine ones to find the minimum needed changes in both projects.

Regards,
Andrey
