They aren't in e.g. a __XEN_TOOLS__ protected region after all. (I don't mind their removal, but in public headers I think we need to be double careful.)
The reasoning is all in the commit message: those macros haven't made any sense since ages. In case someone is using them, the usage is either wrong or not related to Xen. I have checked Mini-OS, Qemu and Linux kernel for uses and didn't find any. Juergen
