You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

You need something like 1540 to compile 2.4.21 with gcc 3.3.2. 1540 was
