Ah, missed those comments - thanks for the pointers.

It's beyond my expertise right now too. We change from having to  
trick ld.so into doing something funny to having to trick ld and  
ld.so into doing something funny. :) I think I'm just going to hack  
past this problem right now using the old string.C versions of the  
functions I need, but I'll tackle it in a few months I guess.
