I supposed this wasn't built by default and I missed it, but it looks to be built unconditionally. I wonder why I didn't see this. Defining XC_WANT_COMPAT_MAP_FOREIGN_API while building is one way to fix, or else kdd would need to switch to the new interface. The latter is obviously better long term, but the former is done for a bunch of stuff in tree so it might as well be done here too. The machine with the trees I used for this work is currently unavailable (network issues in our office), but I'll see if I can reproduce.
