Win32 defines two macros called min and max (in windef.h); these can 
conflict with the ANSI C++  min and max template functions.  This 
happens if you #include windows.h and one of the ANSI C++ headers that 
declare or call the template min and max functions. 

However,  MS's  min/max can be disabled by putting the line 
#define NOMINMAX
 before the #include of windows.h. (the min and max macro definitions 
are enclosed in an #ifdef NOMINMAX block in windef.h).

Since the stationery uses precompiled headers you will need to change 
the .pch++ file and precompile the MSLHeaders again.

In the Windows precompiled headers project

Win32-x86 Sup****t
   Headers
      Precompiled Headers
         Win32Headers.mcp

Open the .pch or .pch++ file and for example Win32Headers.pch

#pragma precompile_target "Win32Headers.mch"
// #pragma once on
#include "ansi_prefix.win32.h"
#include <windows.h>

change that to
#pragma precompile_target "Win32Headers.mch"
// #pragma once on
#include "ansi_prefix.win32.h"
#define NOMINMAX
#include <windows.h>
