[ODE] compiler crash / trimesh collision questions

[Shamyl Zakariya]

I don't know anything about OPCODE's Hybrid Model, but regarding your 
CodeWarrior question, is there any reason why CodeWarrior projects 
cannot link against a lib built by GCC? The standard makefiles build 
ODE/OPCODE using GCC and it works just fine ( well, I'm not using ODE 
CVS, rather the 0.5 release ).

For my work I build ODE on the command line and build a static lib. My 
programs link against that static lib and everything's hunky-dorey.
