I can't debug Comment 6 in Xcode 3.1.4's gdb on powerpc-apple-darwin9. When I
try to load the compiler into gdb, I get the error...

.gdbinit:12: Error in sourced command file:
../../gcc-4.8-20121024/gcc/gdbinit.in:186: Error in sourced command file:
Command not implemented yet.

If I ignore that and set 'break tree-ssa-loop-ivopts.c:4135' and run the
compilation command in gdb, I get...

/proc/self/exe: No such file or directory
