ATOMIC_OPS.cpp configuration test failed on MSVC8.0-x64 due to undefined external symbol _InterlockedIncrement.
Because of this _RWSTD_NO_ATOMIC_OPS macro has been #defined in config.h.
The InterlockedIncrement() function defined only in Win32 platform (located in kernel32.dll). At x64 platform this function is declared, but kernel32.dll doesn't exports this function. The MSVC8 injects code of the function instead of call (so called intrinsic function).
