$ ./bin/gcc -v
Using built-in specs.
Target: mips-sgi-irix6.5
Configured with: ../trunk/configure --prefix=/usr/people/francois/devel/irun

Thread model: posix
gcc version 4.3.0 20071107 (experimental) [trunk revision 129965] (GCC)

On mips-sgi-irix6.5, -g uses dwarf2. Using -gstabs instead of -g make it pass.
