Interesting, I couldn't remove libstdc++.so.5:

$ ls -l /usr/lib | grep libstdc++.so*
lrwxrwxrwx  1 root root       18 2008-04-07 06:14 libstdc++.so.5 ->
            libstdc++.so.5.0.7
-rw-r--r--  1 root root   737624 2007-01-03 13:47 libstdc++.so.5.0.7
lrwxrwxrwx  1 root root       18 2007-04-22 09:40 libstdc++.so.6 -> 
            libstdc++.so.6.0.8
-rw-r--r--  1 root root   909044 2006-12-10 09:45 libstdc++.so.6.0.8 

$ sudo aptitude remove libstdc++.so.5.0.7
...
Couldn't find any package whose name or description matched
"libstdc++.so.5.0.7" 

It occurred to me that something else might need libstdc++.so.5, and so
decided against removing it, for it does not harm there, even if not
needed by this particular application.
