I don't know, but here is a suggestion:

The original Bison was written by Robert Paul Corbett for his thesis work
at Berkeley. Then somehow RMS acquired and adapted this Bison for GNU.

RPC then went on adapting Bison for further Berkeley projects; I think it
might be called "Berkeley Yacc" or something (make an Internet search for
Bison at Berkeley if you want to find out).

So the GNU version would get the GNU copyright notice, and the Berkeley
version would get the BSD copyright notice.
