kibstdc++3 dependency

Hello,

I have an application that was built on a RedHat AS 2.1 machine and there is
a dependency on libstdc++3. The RHAS 2.1 machine has the
libstdc++3-3.0.4-1.i386.rpm package but there is no such package on RHAS30
so my app will not startup as there is no libstdc++3 package on RHAS30.

In /usr/lib libstdc++3 is really a libstdc++.so.3 and on RHAS30 there is a
new libstdc++.so which is a link to libstdc++.so.5. RHAS 30 actually
packages libstdc++-3.2.3-20.i386.rpm. I tried to make a link
libstdc++.so.3 -> libstdc++.so.5 but now I get missing symbols when running
my app:

_ZNSt13_Format_cacheIcE6_S_getERSt8ios_base
_ZNSt13_Format_cacheIwE6_S_getERSt8ios_base
_ZNSt13_Format_cacheIcEC2Ev

I wondered why the RHAS30 stdc++ is not backward compatable with apps linked
against the stdc++3 libs. I'm looking for options to get an app compiled on
RHAS21 to work on an RHAS30 machine. Why did the new stdc++ library get rid
of the Format_cache functions. Thanks.
