confirmed on a cross from x86-64-darwin10 => powerpc-ibm-aix6.1.3.0
with gcc-4-6-branch r181845
using cvs binutils (2011/11/30).

using gcc-4.6-svn-r180685 as the bootstrap compiler.

also on a cross from powerpc-darwin9 => powerpc-ibm-aix6.1.3.0

4.7.0 trunk (r181818 & r181773 resp.) builds OK (on powerpc-darwin9,
x86_64-darwin10)

is this a regression in the 4.6 branch (i.e did 4.6.0/1 work?)
