The patch is for readelf, which doesn't use libbfd.  (And if readelf 
should use gnulib for this?  I don't know, seems overkill for a single 
function).

I think "growing" and "lot of" don't describe the effort.  Rewriting to 
use gnulib (and the corresponding necessary testing) might be trivial as 
well (though I don't think so), but the returns are still very small.

Depends on the definition of old.  For instance our oldish enterprise 
stuff (SLES12) still has current binutils, so at least there it's tested 
relatively good.  OTOH it's only 9 years old, so some might say that 
doesn't qualify :)


Ciao,
