Nej, for der er tale om forskellige C++-ABI'er. Man kan ikke linke
C++-kode oversat med gcc3.2 med C++-kode oversat med tidligere
gcc-versioner.

Den største forskel mellem libstdc++-yadda.yadda.yadda.so.3 og
libstdc++.so.5 er simplethen at de svare til to forskellige
C++-ABI'er.

gcc-3.0 brugte vidst libstdc++.so.4, men det blev heldigvis rimelig
hurtigt klart at der skulle atter en opdatering til ABI'et, så
distributionerne var ikke begyndt deres transition.
