Hallo, I have to install a sw , trough tarball, which requires an upgrade gcc-3.2 to 4.1/4.3. Now, who knows if it possible to upgrade gcc 3.2 to 4.1/4.3 , and leave the w3 workstation base system ? . Or must i have to upgrade/reinstall the platform to the ws5 ? Thank you very much. Best regards Claude Angéloz
