Here is what I see in a 32 bit intrinsic build (cygwin). Now, this is not
jumbo-5, but I did not think anything changed about how md5_gen is built,
since then.

$ ../run/john -test -form=md5-gen
Benchmarking:  md5_gen(0): md5($p)  (raw-md5)  [SSE2 16x4x2 (intr)]... DONE
Raw:    9653K c/s

Benchmarking:  md5_gen(1): md5($p.$s)  (joomla)  [SSE2 16x4x2 (intr)]...

Many salts:     8321K c/s
Only one salt:  5404K c/s

I will later check this on my pen drive linux-64 system, to see if there are
problems showing up there, which do not appear on this 32 bit build.

Jim.
