Bug ID: 39101
           Summary: Visual Studio Compiler creates invalid interface from
                    a typelib
           Product: Wine
           Version: 1.7.49
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: oleaut32
          Assignee: wine-bugs@winehq.org

Sample Project
winetricks vc2008express
Open the Attached project and compile.
StdAfx.h has line.
#import "../typelibs/Debug/typelibs.tlb"
which causes the compiler to get generate typelibs.tlh and typelibs.tli files. 
These files represent the interfaces that are defined in the TLB.
Under WINE, the file created (runme\Debug\typelibs.tlh),
contains a line, like below, for every function in the base interfaces(s).
virtual HRESULT _VtblGapPlaceholder1( ) { return E_NOTIMPL; }
whereas on windows these lines aren't there.
These extra lines cause the V Table to be incorrect and programs crash when any
of the interface functions are called.
