    I discovered something interesting tonight... the supplied FreeBSD
binary at texas.net is about 30% faster than the one I compiled from
source using the i486-gcc target:

rc5-56-client: Start Key 0xAF038920000000, trying 268435456 keys.
rc5-56-client: Processed 148861.40 keys per second.
rc5-56-client: Keyspace Exhausted in 30.05 minutes.

... compared to:

rc5-56-client: Start Key 0x98C3A980000000, trying 268435456 keys.
rc5-56-client: Processed 192839.87 keys per second.
rc5-56-client: Keyspace Exhausted in 23.20 minutes

    Anyone know how the binary client was compiled?  The Makefile that
comes with the source has some pretty nasty gcc optimization flags.
