[ODE] recent dSetZero() patch wrong?

[Aras Pranckevicius]

Hi,

I suspect the recent dSetZero() eliminating patch to be wrong in one place.
I've tried it myself, and now it's also in CVS...

It did make StepFast working incorrectly. The cause was in stepfast.cpp,
around line 740: "dSetZero (J, 2 *
m * 8);" shouldn't be commented out. I don't know the "meaning" of it, but
it seems from the code that dSetZero is actually needed there...
