Have you gotten any reports on the c version and sparcs?

Please? We have several ppros here in the office and your version 2
486 or p5 code is still the fastest for them(except for the cyberian
client). The bovine v2.4 is faster(except for cyberian) on our p5 machines.

On a ppro at 233, under NT and no load, the stats are as follows:

486 code:  569K
6x86 code: 524K
p5 code:   569K
bovine v2.4 gui: 537K
cyberian v3.4: 615K  <- so there is still room for improvement!

At home the 6x86 pr166 gets 270K or better with your code under linux.
If you want me to beta-test on a 6x86, my home email is marcus at dfwmm.net
(that's our team name as well).

Have they(bovine) contacted you yet?
