This is a Bison version problem. Since Homebrew's Bison installation
doesn't override the macOS system-provided Bison (which is too old), you
need to explicitly pull it in before doing the configure:

$ brew_opt="$(brew --prefix)/opt"
$ export YACC=$brew_opt/bison/bin/yacc

Are you using the configure_octave.sh script from my octave-build
repo[1]? That should take care of this for you. If you follow the steps
in its README, Octave should build right out of the box.

Cheers,
Andrew
