I fully agree with both of these

Right now, md5_gen has a 'trival' unicode support. It would be nice to be
able to keep the trival, but also add utf8->unicode support. I currently
only have 7-bit ASCII to unicode. Simply converting bytes into words.

I agree with this one also. I can not use intrisics (well, I 'can' build
with them, but 32 bit gcc sux), but for people that do have 64 bit systems,
this is a HUGE speedup, almost as much as going from x86 to original SSE2 in
asm is on the 32 bit builds.
I am not sure whether these are prime time 'ready' for a J-2. However,
isn't the even builds, builds that add new stuff, and the odds usually are
bug fix/performance fix releases?
I do not believe that intrisics as writting (other than in md5_gen) are
'ready'. I am pretty sure that intrisics replace most of the formats they
use, vs working with them IIRC.
As for utf8 to unicode, it can probably be done without ifdef's by making
changes in the init() functions of the formats, to change the proper
function pointers (and possibly testing vectors, when the command line lists
utf8). I am pretty sure that is what Magnum did in the end, and if not, it
can readly be done. In that way, a single build (without having to do a
'special' uft8) would properly give you all the usablity you need, based
upon command line driven switches.
Jim.
