Why this one is particular (and not the other ap_queue*() functions)???

I really makes few sense to me, and smells something like
"-Wl,--whole-archive,-lmain,--no-whole-archive" is missing at link
time. Without it, libtool (or?) seems to have some heuristic to detect
whether the functions are "really" used and does not include them
otherwise.
It bit me quite somes times already (not in httpd, though), and never
really understood why...
I'{d,ll} try this for testing...

Yann.
