commit dbd662300b77739e702574fbd2f9167070e58c21 Author: Corinna Vinschen <[email protected]> AuthorDate: Mon Jan 20 13:27:57 2025 +0100 Commit: Corinna Vinschen <[email protected]> CommitDate: Mon Jan 20 13:27:57 2025 +0100 Cygwin: seteuid: set errno if TranslateNameW fails The call to TranslateNameW in s4uauth can fail and the code leaves the function indicating an error, if so. It just misses to set errno in this case, so add that.
