[ODE] building ODE on Athlon 64

[Julien LOLLIVIER]

I tried this patch, and it works perfectly. But enabling Opcode always generates a lot of warnings (see my previous post), and we always encounter crash in our applications :

Program received signal SIGSEGV, Segmentation fault.

There's something strange : with a little Trimesh (less than 1000 triangles, I think), no crash appends.

Any clue ?
