 OK, thanks for the clarifications. I wasn't aware of this ABI change back 
 then.

 I understand these concerns. We build our library by 3 or 4 different 
 compilers and a total of 10 different versions or so :-(

 Does this still hold given DJ's mail?

 I might if I could. I have no knowledge of gcc, libiberty, etc at all. My 
 place is gnats, beyond that I can only try to get patch creators and 
 reviewers into contact -- usually a fruitless endeavor...
