Corinna,

sorry, I missed that early announce. Is there any link? Since I'm aware
only of almost "last minute" MSYS2 mail [1] referring to your recent
announce.

If I understood you correctly, previously discussed changes in Cygwin
itself are not considered anymore and from now Wine is really left
alone with this issue?

Regards,
Andrey

[1] Announcement: msys2-runtime 2.5.1 -- last version to support XP/2003
    30. June 2016
    https://sourceforge.net/p/msys2/mailman/message/35191999/

P.S. I didn't receive your message also. Does Cygwin mailing list
program strips my E-Mail address (though I see it in the archive)?
(And it even can't guess a possibly follow-up :( )
