Bug #: 33020
           Summary: GetLongPathName does not properly resolve the relative
                    string '.'
           Product: Wine
           Version: 1.5.24
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Calling GetLongPathName on a string containing the self-referencing string '.'
returns a bogus path, for example:
GetLongPathName('shortpath.')
returns
shortpath\shortpath
instead of
shortpath.

This poses a problem for Silverlight, which uses this feature (for some odd
reason) to find the path for debugging DLLs.
