[ODE] ODE and Itanium processors

[Bram Stolk]

Hi,

I can confirm that OpenDE SVN version works on itanium, if the
guard for -fPIC is removed from ode/src/Makefile.am

This was tested on a 20-processor shared memory beast:
SGI Altix with itanium2 processors, using gcc 3.4.0
(a multithreaded opende would be an interesting experiment
  for this iron).

I've also tried the intel compiler icc version 9.
These are my findings:

- configure thinks its a GNU compiler (see below). Why?

- I need -lcprts on the commandline for the test programs

- drawstuf dstest works

- test_ode fails to build
   /opt/intel/cc/9.0/lib/libunwind.so.6: undefined reference to `?1__serial_memmove'
   Strangely, other tests do build, even though they are more complex.

- other ode tests give segm violation.
   See below.

- virtual func override warning. See below.
