The GNU tools have handled cross-compilation for decades, so I don't find this answer convincing as stated. Nothing needed to change to make cross-compilation work. The lib64 directory does not exist for cross-compilation. It exists because the kernel supports two different native ABIs. I strongly support the idea of a compatibility symlink so that older gcc releases will continue to work. Ian
