compile libstdc++ 2.7.2?

netscape: error in loading shared libraries: /lib/libstdc++.so.2.7.2: i
undefined symbol: __register_exceptions

Is is possible to make libstdc++ 2.7.2 run on a system that's been
converted to glibc 2.1?  I get the above error when trying to run 
netscape.

I remember reading somewhere that it's not possible to compile
the 2.7.2 libs with newer gcc/egcs.  Has there been a patch?

This are the libraries that netscape is linked against.
