I thought this was fixed by adding an underscore in front of all CPU_TYPE_XXX items in MachO.h that exactly matched macros in machine.h... It is really lame that a header file in LLVM is using macros that exactly match enums.

I completely agree, but alas we are stuck with this on MacOSX.

No one should be including it manually as we shouldn't have ANY code depending on platform specific headers. Try preprocessing your file and see who includes machine.h.
