RE: [boost] [shared_ptr] InterlockedIncrement rocks!

I just took your implementation (http://www.pdimov.com/cpp/shared_count_x86_exp2.hpp) for shared_ptr and use it now in win32gui (upcoming v1.4.2). Using Interlocked* for win32 totally rocks!
From my tests - Interlocked* are very fast. They're about twice as slow as a raw increment (or my tests are wrong;)).
From what I see - I think you can certainly merge them into boost::shared_ptr. Maybe users can select the old version or this Interlocked* version with a certain macro - like BOOST_SHARED_PTR_USE_INTERLOCKED.
Also, why not including windows.h directly, like this: #define WIN32_LEAN_AND_MEAN #include <windows.h> <snip>
"Lean" is a bit of a joke. A rather smaller set of Windows definitions can be included by defining an architecture-identifying macro (e.g. _X86_ for i386) followed by: #define NOMINMAX // inhibits definition of min and max macros in // <windef.h> #include <windef.h> #undef NOMINMAX #include <stdarg.h> // <winbase.h> requires definition of va_arg #include <winbase.h> Unfortunately this still defines quite a few macros. The MSDN Library documentation of Win32 functions will tell you about any additional headers that need to be included, even though it recommends you include <windows.h> instead.
