I'm not sure we are talking about a hard requirement to update
binutils.  The old version works.  There are a few instances that
could cause confusion but which could be solved with a FAQ entry that
says to upgrade binutils to some version to get more specific error
messages (ie.  Unresolved symbols in the output from ld would not
pretty-print but would show raw mangled form).

As for GDB, I think it does become non-negotiable to upgrade that in
order to get anything but the most rudimentary debugging support.  I
have to ask, though, how many people who are using a bleeding-edge
version of gcj will be unwilling to update to a new version of GDB?  I
would think that it will be some years before non-free OS's (I am
specifically thinking of things like the "companion cd" for Solaris)
will include GCC 4.1 (or whichever version this patch makes its way
into) anyway.

That's why there is a "-a" version of the patch which doesn't do that!  :)
