So why is this showing 4.2.0 when gcc 4.5.0 was used to build this?
Perhaps that's the latest API ???
Please reply to the mailing list, not just to me. Thanks.
I replied to you, since you replied only to me - not the list! I've set to
"reply-to" field as the list now. IMHO, that should be the default, but I think
that is like religion - you will never get agreement over it.
That is telling you that it does not need anything from libgcc_s.so.1
that is more recent than that is available in gcc_4.2.0. That is
normal.
But this is uninteresting. What I was hoping it would show you is the
versions *defined* by libstdc++.so.6, not the versions that it uses.
I suppose it's possible that libstdc++.so.6 doesn't define any versions
on Solaris; what happens when you run elfdump -v on libgcc_s.so.1? Do
you see version definitions, or only version uses?

And here's what I thought was a library from gcc 3 4.3, though that seems highly
unlikely due to the references of gcc versions up to 4.3.
