Since the upgrade to gcc-4.3, gcc has started to ICE on selected
packages. After some debugging, all cases so far seem to relate
to using -funroll-loops, so I'll start putting all ICE's to same
bugreport.
Using built-in specs.
Target: arm-linux-gnueabi
Configured with: ../src/configure linux gnueabi
Thread model: posix
