[ODE] Re: ODE (and mainly OPCODE) for 64bits

[Flavien Brebion]

The "bad" one. I was running short on time and had to make the damn 
thing work, no matter
how :)

But honnestly i didn't care much about the memory usage. The application 
into which i've integrated
it requires Gigabytes of RAM anyway, so a bit more or a bit less... 
performance was more
important, but as i said it ended up being very acceptable.

Yeah it still compiles on 32 bits systems. It was a matter of redefining 
a new type ( with some
#defines depending on the OS ) and replacing pointers here and there by 
the new type. It's
a bit different than the "official" version though, since i applied a 
few other changes of my
own, namely support for saving / loading OPCODE's data structures to the 
disk ( to avoid
regenerating them on the fly each time ) and two-sided collisions for 
mesh vs capsules.
