[ODE] Trimesh collision: not all triangles are colliding

[Frederic Marmond]

Hi,
On which platform are you working?
Linux?
If yes, I found a bug in the OPCODE library, that forced me to compile 
the collision part without optimisation for a file (-O0), on gcc-3.x 
compilator. Worked fine (-O3 for all files) with a gcc-2.95 one. The 
result was as you said, some triangles collides, others don't as they 
would have been colliding.

If you are in this situation, ask me, and i'll try to find in my 
archives precisaly which caused the problem, and a test-case that 
reproduce the problem.
