if asking for an A record for a given name hits and cname, and it's
legal to put the CNAME and the CNAME data's A record (albeit with a
different owner name) in the answer section of a dns response, then
why is my named complaining about 

Jul 24 11:36:20 noc named[98]: wrong ans. name (m.doubleclick.net != uuvald2avip.doubleclick.net)

which, i am almost certain, stems from the fact that m has multiple
cnames.  i get, for example:

;; ANSWER SECTION:
m.doubleclick.net.      5M IN CNAME     exnjld1avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     ancald2avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     ancald1avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     anvald2avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     anvald1avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     uucald2avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     uucald1avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     uuvald2avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     uuvald1avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     exnjld4avip.doubleclick.net.
m.doubleclick.net.      5M IN CNAME     exnjld1bvip.doubleclick.net.
exnjld1avip.doubleclick.net.  1H IN A  209.67.38.35

which obviously has multiple CNAMEs, but only one A is returned (this
is by asking the authoritative server, if i ask my own, i get only one
cname and the single a record).

shoud i perhaps be getting back more a records?

or do i have to turn on multiple-cnames locally in order to peacefully
coexist with this kind of set up?
