Duh. I thought "cq" and wrote "qu". Thanks :)

It might be safe to use __builtin_alloca everwhere we have alloca.
(Didn't AG already submit a patch for that?)

One possible explanation is a broken ar. Another (more likely, IMO) is
command line length limits: if libtool runs ar in one sweep it's probably
fine, but if it must split the command, the 2nd invocation will operate on
an existing archive, in which case the existing members are subject to
replacement.
I can't think of any reason we wouldn't always want to use "q" for
AR_FLAGS. You might want to explain your problem on the libtool mailing
list, to see if they have other ideas:
