Attempting to bootstrap gcc-4.6-20100828 on armv5tel-linux-gnueabi fails in
stage 2 with:

The first error in arm_ge_pcs_model () was reported 11 days ago as PR45321. 
The other 'uninitialized const member' warnings/errors are new since then.  I
can't see any obvious recent changes in arm.c that would explain them, so I
suspect they're caused by some C front-end change.
