There:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms683615(v=vs.85).aspx

They say:
"This function is implemented using a compiler intrinsic where possible. For more information, see the WinBase.h header file and _InterlockedIncrement64."

The 64bit intrinsic isn't available on 32bit like said in the page you refer, but this should mean that windows.h should export this function anyway and implement it without the intrinsic. But that doesn't fit with the error you get.
