http://gmplib.org/ is the new place. Speaking of that, anyone know where to find up-do-date snapshots (e.g. a CVS repository) of GMP? The status page hints at a minor update this month and I'd like to preview the changes if possible to see if there's anything build-related.
The nettle patches are only related to a peripheral stuff like docs and test programs, right? I've built nettle 1.15 separately for our internal purposes without any patches and I'm not aware of any incompatibilties.
