 Microsoft describes the signature of {{{_InterlockedExchange}}} as
 {{{
 extern "C" LONG  __cdecl _InterlockedExchange(LPLONG volatile Target, LONG
 Value);
 }}}
 See http://msdn2.microsoft.com/en-us/library/f24ya7ct(VS.71).aspx

 In boost/detail/intrinsic.hpp, this function gets declared as
 {{{
 extern "C" __declspec(dllimport) long __stdcall InterlockedExchange( long
 volatile *, long );
 }}}

 The problem is that {{{LPLONG volatile}}} is equivalent to {{{long *
 volatile}}}, not {{{long volatile *}}}. This results in compilation
 failures in the presence of a correct declaration of this function; i.e.,
 the compiler complains that you cannot overload C functions.
