The problem is still present when the cross compiler is compiled at -O0. 
I tried to build it with gcc 2.96, 3.2.3 and 3.3.5. I currently don't 
have access to gcc 3.4 on an ia64 box.

I also tried to run gcc with "-da", which gives me a lot files, with a 
content that I don't understand. I have done the same on an i386 arch, 
and there is some differences:
