--- Comment #1 from Marcos Gutiérrez Batz  ---
I've been hit by the same problem, the problem lies in the interface
IFileOperation of the shobjidl.idl, the function:

HRESULT NewItem([in] IShellItem *folder, [in] DWORD attributes,
                    [in, unique, string] LPCWSTR name, [in, unique, string]
LPCWSTR template,
                    [in, unique] IFileOperationProgressSink *sink);

While the Windows SDK file counterpart:

HRESULT NewItem(
        [in] IShellItem *psiDestinationFolder,
        [in] DWORD dwFileAttributes,
        [in, unique, string] LPCWSTR pszName,
        [in, unique, string] LPCWSTR pszTemplateName,
        [in, unique] IFileOperationProgressSink *pfopsItem);

This is show with just this simple test:

$ cat test.c

#include <shlobj.h>

void main(void)
{
}

$ winegcc test.c 
$ wineg++ test.c 
In file included from /opt/wine-devel/include/wine/windows/shlobj.h:27,
