error C2371: 'WCHAR' : redefinition; different basic types

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi all, I've been haunted by this problem for quite a while. I've done
a lot of search on the internet but haven't found any solution to
this. I'm building an MFC program with ODBC support and got the
following error:

c:\program files\microsoft visual studio 8\vc\platformsdk\include
\odbcss.h(430) : error C2371: 'WCHAR' : redefinition; different basic
types
c:\program files\microsoft visual studio 8\vc\platformsdk
\include\winnt.h(266) : see declaration of 'WCHAR'

In odbcss.h I found

#ifdef UNICODE
....
#else
typedef char DBCHAR;
#endif

In ocdb.h I found

#if !defined(OLE2ANSI)

#define LPDBSTR LPWSTR
#define DBCHAR WCHAR
....

And in winnt.h I found

#ifndef _MAC
typedef wchar_t WCHAR; // wc, 16-bit UNICODE character
....

Which seems to be a bug to me. I've seen this issue being raised many
times during my search but none of them is fully answered. Is there a
suggested solution to this at all?
