MemoryFence() and MemoryBarrier() are both macros so #undef'ing them should work and if their functionality is needed then the Win32 ReadBarrier/WriteBarrier/ReadWriteBarrier functions (or their underscore-prefixed intrinsics) should be substitutable.

Are they macros or functions?  If macros, why not just #undef them at  
the top of Atomics.h?
