Oh, there it is, sorry.  :-(  I even commented on this before.  Brain

I'm not seeing guaranteed compile-time constants for detecting
compile-vs-runtime differences?

Should the API guarantee that a query with "return_ap_information" set
to GETDNS_EXTENSION_TRUE will get a response with that data, even for
something like a query for an empty string, or a NULL pointer as the
name field?  When I do a check at start-up, it might be before a user
privilege transition, so a stable query guaranteed to not hit the wire
is helpful.
