Package: gzip
Version: 1.3.5-14

please define UNALIGNED_OK when building the amd64 target... unaligneds 
are very inexpensive on all intel and amd cpus.

i benchmarked gzip -9 on linux-2.6.17.tar with this define and i see a 
2.5% speedup on p4, a64, and a 9% speedup on core2.

note that this wasn't necessary on 32-bit x86 because there's custom 
32-bit assembly which uses unaligneds even more aggressively than the C 
code does when given UNALIGNED_OK.
