           Product: Wine

          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
          Assignee: wine-bugs@winehq.org
          Reporter: huangqinjin@gmail.com

errorlevel was changed to 0 after SET, while Windows CMD keep it unchanged.
Quote from https://stackoverflow.com/a/34968021 and
https://stackoverflow.com/a/148991:
The differences between .CMD and .BAT as far as CMD.EXE is concerned are: With
extensions enabled, PATH/APPEND/PROMPT/SET/ASSOC in .CMD files will set
ERRORLEVEL regardless of error. .BAT sets ERRORLEVEL only on errors.
test.bat:
@echo off
call :SetError
echo %errorlevel%
echo %errorlevel%
SET x=
echo %errorlevel%
exit /B 0
:SetError
exit /B 2
