FWIW I am using a native gcc on x86_64 to build cross *-rtems4.11 targets.  

gcc (GCC) 4.7.0 20111029 (experimental)

I think this is a native issue (x86_64-unknown-linux-gnu) that is showing up on
multiple odd situations.

I see this compiling arm-rtems4.11

And I think this is the same thing I saw with the native compiler of
yesterday's vintage compiling the head of binutils-cvs to target
sparc-rtems4.11

/users/joel/test-gcc/binutils-cvs/src/bfd/sunos.c: In function
‘sunos_check_dynamic_reloc’:
/users/joel/test-gcc/binutils-cvs/src/bfd/sunos.c:2328:1: error: dominator of
26 should be 20, not 19
/users/joel/test-gcc/binutils-cvs/src/bfd/sunos.c:2328:1: internal compiler
error: in verify_dominators, at dominance.c:1041

I can provide preprocessed source if someone needs it.
