I'm not sure if I agree with that.  I'd prefer if these files remained 
unmodified because differences threaten portability across distributions.

Is anyone except Fedora compiling current glibc versions with the 
--enable-obsolete-* flags?  Then we'll need a more intelligent ABI 
differ.  (If it's just Fedora, I'd prefer moving Fedora forward.)

Thanks,
Florian
