   You really haven't seen my scheme in action. Check out the current
   RedHat rawhide. They have 2 C++ compilers. egcs 1.1.2 is used to
   compile KDE.

   # ls  /usr/lib/libstdc++* 
   /usr/lib/libstdc++-2-libc6.1-1-2.9.0.so   /usr/lib/libstdc++-libc6.2-2.a.3
   /usr/lib/libstdc++-2-libc6.2-1-2.9.0.a    /usr/lib/libstdc++-libc6.2-2.so.3
   /usr/lib/libstdc++-2-libc6.2-1-2.9.0.so   /usr/lib/libstdc++.so.2.7.2
   /usr/lib/libstdc++-3-libc6.2-2-2.10.0.a   /usr/lib/libstdc++.so.2.7.2.8
   /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so  /usr/lib/libstdc++.so.2.8
   /usr/lib/libstdc++-libc6.1-1.so.2         /usr/lib/libstdc++.so.2.8.0
   /usr/lib/libstdc++-libc6.2-1.a.2          /usr/lib/libstdc++.so.2.9
   /usr/lib/libstdc++-libc6.2-1.so.2         /usr/lib/libstdc++.so.2.9.dummy
   # rpm -qf /usr/lib/libstdc++-2-libc6.2-1-2.9.0.so
   kernelcc-c++-1.1.2-4
   # rpm -qf /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so
   libstdc++-2.96-33

And you honestly believe this is a good thing?  It illustrates that
the libstdc++ are failing to properly version their library (which is
somewhat understandable since they've punted binary compatibility for
C++ until GCC 3.0).  And by giving them your "interface scheme" you've
provided them with the means to get away with it.  Just slap a
different soname on every permutation of things and you're not very
likely to get complaints about binary incompatibilities.

You see that you have both: libstdc++-2-libc6.1-1-2.9.0.so
and:                        libstdc++-2-libc6.2-1-2.9.0.so

I think those should be binary compatible (assuming this is a system
where glibc 2.2 is the installed system C library).
