dnl OLD: We prefer byacc or yacc because they do not use `alloca'
dnl
dnl CURRENT: We don't mind `alloca', but we do mind `bison -y' because
dnl          newer versions of `bison', with `-y' complain about %expect and
dnl          anything that yacc didn't document.  Because `bison' typically
dnl          also installs a `yacc' link that acts like `bison y', we put
dnl          `yacc' last in this list.
