+// This header file is required to work around collisions between the defines in mach/machine.h, and enum members
+// of the same name in llvm's MachO.h.  If you want to use llvm/Support/MachO.h, use this file instead.
+// The caveats are:
+// 1) You can only use the MachO.h enums, you can't use the defines.  That won't make a difference since the values
+//    are the same.
+// 2) If you need any header file that relies on mach/machine.h, you must include that first.
+// 3) This isn't a total solution, it doesn't undef every define that MachO.h has borrowed from various system headers,
+//    only the ones that come from mach/machine.h because that is the one we ended up pulling in from various places.
