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]

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.
