Also this needed at top after #includes:
+#ifndef TARGET_ABI_OPEN_VMS
+#define TARGET_ABI_OPEN_VMS 0
+#endif

Thanks, good pointer. I found what you mean based on your recommendation. I
tried many things like it then. Nothing worked. I don't know why.


Notice that there is __builtin_foo and foo.
Darwin appears to only rename __builtin_foo.
I need to rename foo.
I didn't figure out what the implicit builtins are, but I don't think
figuring that out would help me.


This is a little bit lame but worked:
