The contract of AC_PROG_YACC is to find something that will generate
parsers from POSIX-compliant input; all three of bison, byacc, and
classic yacc are considered.

We would be happy to take contributions of AC_PROG_BISON (and
AC_PROG_FLEX), but as you know there isn’t anyone doing active
development of Autoconf right now, so it’s not going to happen without
someone stepping up.
