I'm ending up pretty much confused here... (:-/) I checked into my
various libraries, and I find the ones in /boot/develop/abi/x86/gcc4/lib
are just links to those in /system/lib/gcc4, so there's nothing to 'replace'
from there. OTOH, I dug down into the build tree and found libxxx++.so
in generated.x86gcc4/objects/haiku/x86/release/libs/stdc++/current/
which, when I replaced the ones in /system/lib/gcc4, did indeed fix the
problem!
I don't understand where those libraries actually came from, though
I don't see any sources in the tree, and they aren't in the gcc.4.4.4 zip
I have (via installoptionalpackage, I guess). There are '.a' files in the
archive,
but I think they match the vintage of the other older ones, anyway

I read that one as relevant to cross-compiling only, but I guess I'm
not sure of what's involved here. The (closed) one I came across
is #5322.
Anyway, I guess it's solved now. Just wish I understood why!
