Thanks Joel.  I'll copy that or the gcc wording.

It looks like the earliest binutils files that are edited by
update-copyright.py have copyright dates starting at 1985.  Of those,
quite a few have skipped years.  eg. binutils/filemode.c is
Copyright 1985, 1990,...

So, CVS goes back to 1991, and there are copies of old binutils
releases for all years from 1988 to 2002 except for 1999 at
ftp://sourceware.org/pub/binutils/old-releases/

Joseph, do you know why implicitly adding years to the claimed
copyright years is a problem?  I'm guessing the file needs to be
published somewhere for each year claimed.
