[Bug 35412] New: wine's cmd fails on if not exist foo\nul

http://bugs.winehq.org/show_bug.cgi?id=35412

Bug ID: 35412
           Summary: wine's cmd fails on if not exist foo\nul
           Product: Wine
           Version: 1.7.11
          Hardware: x86
               URL: http://www.tinycc.org/
                OS: Linux
            Status: NEW
          Keywords: download, source
          Severity: minor
          Priority: P2
         Component: cmd
          Assignee: [e-mail]
          Reporter: [e-mail]
    Classification: Unclassified

TinyCC's build script does:
if not exist libtcc\nul mkdir libtcc

this fails, and libtcc is not made. Removing '\nul' works around the issue.

Fixed upstream:
http://repo.or.cz/w/tinycc.git/commitdiff/48ad93983f292b0eab62b8d8cce2abcb50...

but wine still needs to be fixed as well

Does the bug still occur with wine-5.0-rc2?

You can test it yourself. As you've been you before, don't ping others to do
what you can yourself.

I did not understand what the bug is. When I understand t bu and I can test it,
I do it. 
That's why I ask you to test again.

And one more question: what is the purpose to open a bug report if you are not
inclined  to look after it?

To cut to the heart of the issue, old batch interpreter (like Win98) won't
return true for a directory that exists unless \nul is appended.   Newer
versions, like command.com or cmd.exe on Win XP are not affected.

Here's the testcase to clarify the expected behaviour:

```
mkdir test
if exist test echo yes it exists
if exist test\nul echo yes it exists
rmdir test
if exist test echo yes it exists
if exist test\nul echo yes it exists
```

Expected output from Windows XP:
```
Z:>mkdir test

Z:>if exist test echo yes it exists 
yes it exists

Z:>if exist test\nul echo yes it exists 
yes it exists

Z:>rmdir test

Z:>if exist test echo yes it exists

Z:>if exist test\nul echo yes it exists 
```

Unexpected output from wine-2.4.3 (repro the original bug):
```

c:>mkdir test

c:>if exist test echo yes it exists 
yes it exists

c:>if exist test\nul echo yes it exists 
yes it exists

c:>rmdir test

c:>if exist test echo yes it exists

c:>if exist test\nul echo yes it exists 
yes it exists
```

Issue shown above: Wine is always returning true when \nul is used.

Win98 for reference:
```
c:>mkdir test

c:>if exist test echo yes it exists

c:>if exist test\nul echo yes it exists 
yes it exists

c:>rmdir test

c:>if exist test echo yes it exists

c:>if exist test\nul echo yes it exists 
```

In wine-5.0-rc2, the issue is fixed.  The output matches XP:

```
c:>mkdir test

c:>if exist test echo yes it exists
yes it exists

c:>if exist test\nul echo yes it exists
yes it exists

c:>rmdir test

c:>if exist test echo yes it exists

c:>if exist test\nul echo yes it exists
```

Marking fixed.
