Please be patient.  The people who answer questions on this list are
all volunteers who have other, important, work to do as well.

This is the correct list.

In general it is always a good idea to make sure that you are using
the latest release before reporting problems.  In the case of binutils
this is 2.14 (or if you prefer using HJ's versions: 2.14.90.0.6).

It may well be a bug in the bfd library.  if you can provide a test
case (ie the error_msg.o file) we can try to investigate.

For what it is worth this kind of renaming should be possible.  It
certainly does work for a simple test case using the i686-pc-linux-gnu
target and the current binutils sources from the CVS repository.
