problem linking with GCC 3.0 -- undefined reference to `std::codecvt<char, char, __mbstate_t>::id

[Mark Martin]

Here are a couple of additional data points.  I checked the binary rpm from 
the 20010627 snapshot from codesourcery and found that the problem is present 
in the snapshot.  I also built the latest snapshot 20010716 using gcc 2.95.2 
then rebuilt the snapshot using itself.  When I checked libstdc++.a, I found 
that the problem was still present.

My guess is that the compiler is not responsible by itself.  Perhaps the 
older binutils or libraries that I've been using are partly responsible.  Or 
maybe I need to protoize gcc 3.0?

Help!
