The specific problem here is that _shared libraries_ compiled with
glibc 2.0 (or older version of glibc 2.1) can't be used to compile new
programs with glibc 2.1.

As far as compatibility between existing binaries at runtime, it is
fine.  I am happily using the Sparc Linux Netscape with glibc 2.1 and
a recent libstdc++, so it does quite well on the compatibility front.
