[ODE] ODE Unstable Commit: GCC compilation error on x86-64

[Tanguy Fautre]

I just applied a patch that has been on this mailing list for some time 
now (credit: Frederic Marmond).

It fixes the compilation problem of ODE with GCC on x86-64 platforms.
It adds an additional x86-64 assembly patch in timer.cpp and adds a 
x86-64 detection routine in configurator.c.

It's not identically the same patch that was posted, because the 
previous detection routine would erronously detect an x86-64 compilation.

This patch was tested on Debian GNU/Linux unstable, both x86 and AMD64, 
with gcc 3.3.


Note this patch only fixes the compilation of ODE.
ODE compiles and run on x86-64, but *not* yet OPCODE dependent parts 
(the patch is coming along).


Regards,

Tanguy
