http://bugs.winehq.org/show_bug.cgi?id=20991

Summary: EnumRfc1766_create return values
           Product: Wine
           Version: 1.1.34
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mlang
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

EnumRfc1766_create is supposed to return HRESULT values, but returns FALSE in
one case (dlls/mlang/mlang.c:2517) - this should be changed to S_FALSE I guess.

On the other hand the return values of the function are evaluated with the
FAILED macro (see mlang.c:1250) and S_FALSE does not count as failed - so
probably both unsuccessful returns (lines 2504 and 2517) should be E_FAIL?
