Hmmm... that's interesting.  Looking around a bit more, the only other  
places I see any reference to .idata$5 is in bfd/coff-ppc.c around line  
1460.  In this function, the code is trying to find the  
first_thunk_address, but then it doesn't do anything with it (and in any  
case, my target is i386, not ppc) :-(

In fact, the only place where the first thunk is referenced at all is when  
the code is dumping info to the console (presumably via objdump, or the  
like).

Oh well...  as I said, it doesn't seem to affect the runtime execution,  
and I have managed to find a workaround for my needs, so I am happy to let  
it rest.  Thanks again for your feedback.
