No, it doesn't appear to have been regenerated, and is shipping
in the .hc file bundle from the host.

I didn't have it in build.mk (as per building.sgml). I added it
and rebuilt on the target machine, and it still hit stg_ap_v_ret

However, I'll look at Ian's files; he seemed to be doing quite a
few different things here and there, which gives me some
confidence. As you can probably tell, I'd like to nail down this
porting system.
