interlocked.hpp(60) for me is:

extern "C" long __cdecl _InterlockedExchange( long volatile *, long);

intrin.h(198) is:

__MACHINEI(long _InterlockedExchange(long volatile *, long))

where __MACHINEI(X) is defined as X;

so the two declarations should be the same except for the __cdecl. Are you 
overriding the default calling convention?
