Well, such agreement for those files not in GCC (we already have GCC as 
master for libiberty and libdecnumber, for example) - unless and until we 
move the non-shared parts of include/ to a separate directory, which I 
think would be better.  (See 
<https://sourceware.org/ml/binutils/2013-08/msg00207.html> for my comments 
on the division of include/, with an unresolved question about whether 
anything not shared with GCC is used by anything outside of binutils+gdb.)

I consider it necessary that shared files get updated in all the 
repositories between which they are shared (with the possibility of 
removing files when no longer needed by anything in a particular 
repository).
