If it's two out of 25000 source packages whose ABIs might be affected, I 
think that shows it's much safer as a change in glibc than moving to 
_FILE_OFFSET_BITS=64 as a default (which I expect will happen when someone 
puts the work in).  And probably safer than many past changes done through 
symbol versioning.
