Could you give more details of (a) in what circumstances (architecture, 
compiler, etc.) you get this warning and (b) why the truncation is 
correct?

Whatever build failure you got hasn't shown up with build-many-glibcs.py.  
Maybe that should include a configuration with --enable-obsolete-rpc 
--enable-obsolete-nsl to make sure that it tests building those bits of 
code that are disabled by default?
