Changing libiberty, which is shared between projects, would have the 
effect of changing all projects using it (bearing in mind that parts of 
libiberty are under the GPL and parts under the LGPL, and both should 
probably be updated at once).

As such I suppose the copies of licences in the manuals should be updated 
when the common files are updated.  In the GCC tree this means 
gcc/doc/include/gpl.texi and libiberty/copying-lib.texi.  The former is 
*not* a direct copy of the standard FSF gpl.texi, it has local Texinfo 
changes to facilitate generating a gpl.7 manpage - and those must be 
merged in rather than discarded when gpl.texi is updated.

There are six copies of COPYING and four of COPYING.LIB in the GCC tree.  
Of these, libjava/classpath/COPYING and libjava/libltdl/COPYING.LIB appear 
to come from imported components maintained elsewhere, and therefore 
should be updated as part of updates of those components from upstream.

Fortunately --version output says "see the source for copying conditions" 
and so doesn't need to be changed.

I do hope the FSF answer the backporting question 
<http://sourceware.org/ml/binutils/2007-07/msg00057.html> sooner rather 
than later.  With regard to Ian's comment 
<http://sourceware.org/ml/binutils/2007-07/msg00065.html>, I think the 
issue is not so much backports to FSF release branches where it would be 
the FSF releasing under the licence of the old branch, as backports to the 
many different branches used by everyone distributing their own packaged 
stable versions of GPL free software.
