Bug ID: 36946
           Summary: FindFirstFileExW() needs FIND_FIRST_EX_CASE_SENSITIVE
                    support
           Product: Wine
           Version: 1.7.22
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]

FindFirstFileExW() has no support for the FIND_FIRST_EX_CASE_SENSITIVE flag.
Instead it currently returns INVALID_HANDLE_VALUE.

Games affected: Marvel Heroes 2015

The attached patch does not introduce correct handling, but makes the flag
ignored and throws a warning (similar to other places).
