OK, so binutils has been upgraded past 2.23.2-2 in experimental in the 
meantime.  But testing with binutils 2.23.52.20130522-1, I can reproduce the 
same error.

And according to Matthias Klose, this is an intentional behavior change in 
binutils upstream, and it will eventually be uploaded to unstable once gcc-4.7 
and gcc-4.8 updates have filtered through into testing.  Which is why I 
upgraded to this binutils for build testing (along with gcc-defaults -> 
gcc-4.8, make 3.82-1 from experimental, texinfo 5.1 from unstable which is 
stricter about error checking than past versions, etc.).
