GMP passes all 'make check' tests, and ECM-6.0.1 also passes its 'make check' tests, which include a fair amount of factor finding. I did test a couple of known factorizations, and it worked, but not much beyond that.

It may be worthwhile to improve the code if you can, since the release date of 4.2 and status of any improvements for 64-bit PPC are unknown.
