Huh? _Unwind_GetIP() is part of the documented public interface of an
Itanium unwinder. It is available from unwind.h

I have yet to find a use case that needs anything from the HP interface.
It adds a significant amount of code for no gain at all. I am reasonable
sure that the *only* reason people tend to pick it up is bad Googlefu.
Ironically, you won't find it out of the box on Linux either. You will
find unwind.h and the Itanium unwind interface with any recent GCC on
ELF platforms.
