If the appended works for you (be sure to run some tests), I can check
it in.

I wonder if this would really help you, since presumably it would just
reject your bison?

Another option might be to install bison from brew.  In this case it's
probably fine but eventually we may want to require a newer Bison, and
IMO we can't and shouldn't keep catering to Apple's problem
