--- Comment #2 from daube <spam at kdmurray dot id.au> --- Hi all, I've implemented checksum verification using the sha512sums published with prerequisite tarballs on gcc.gnu.org. Please find the patch attached to this ticket. This would be my first contribution to GCC, so apologies if I have not followed some protocol for providing patches. Cheers, Kevin
