Conflict with winapi.hpp and windows.h (manifested in ACE)

Intel C++ 7.0 for Windows, STLPort 4.5.3, boost 1.29, ACE 5.3

Intel was warning a bunch of bad code in my source base, so I turned on
warnings as errors, then I hit a problem where ACE was calling
InitializeCriticalSection with a pointer to its typedef of CRITICAL_SECTION,
and it was using the declaration of InitializeCriticalSection in winapi.hpp.

Turns out, in the standard (by my interpretation), section 7.5/6 that if you
put an extern "C" declaration in a namespace, its also accessible by ::.
The call failed because boost::detail::winapi::critical_section !=
CRITICAL_SECTION.  I ended up ifdef'ing the declaration of critical_section
like so:

#ifndef _WINBASE_ //header guard for winbase.h.  
struct critical_section
{
    struct critical_section_debug * DebugInfo;
    long_type LockCount;
    long_type RecursionCount;
    handle_type OwningThread;
    handle_type LockSemaphore;
    ulong_ptr_type SpinCount;
};
#else
typedef CRITICAL_SECTION critical_section;
#endif

Please advise if you have a better solution.
