  Well, if you're replacing your binutils at the same time, what's the
problem?  The old libs are about to be overwritten in any case!

  The point is, that a distro should have a consistent set of gcc, binutils
and gdb.  Since binutils and gdb live in the same repository, if you either
take a consistent snapshot of the cvs, or if you take gdb and binutils
releases that are roughly-contemporary, they're bound to be 'in-sync' FAPP.

  So if you're building gdb to replace (or even to /be/) your system gdb, you
should already have chosen one that's compatible with your binutils version,
or you should be about to replace your binutils to match.  Either way,
overwriting the old libs won't matter.
