No, I'm sorry I wasn't clear. I am using all of the AIX tools, not Binutils. I 
just assumed that there was something out-of-date with the ld that came with

I have seen this page before, and I'm not sure that it helps me. I'm running 
into the same behavior posted at 
http://gcc.gnu.org/ml/gcc-bugs/2005-04/msg03175.html, where the advice is also 
to look at this page, but there doesn't seem to be a reply from the original 
poster.
