Translations:Upgrading GCC/22/en

So why is this only needed up to GCC 3.4.0/4.1? That's because from that version onwards, GCC uses a forward compatible ABI, which removes the need for rebuilding applications and libraries. Of course, guarantees can never be given indefinitely, but when an incompatibility occurs again, we'll definitely document it here. In that case, the version of the library will probably be increased.
