= Update = In addition to some other 64-bit porting I've done, I've just finished porting hashsum over to 64-bit so it can be compiled on x86_64 architecture (AMD Opteron and Athlon 64 chips as well as Intel Xeon EM64T chips). http://perforce.smee.org:8080/@@//sgl/grimoires/devel/crypto/hashsum/hashsum-64-bit.patch
