dnl byacc on FreeBSD 4.3 gives weird parsing problems.

dnl The bap -d argument only works with bison, so enable it
dnl  if we're using bison.

dnl Unfortunately, the bison internals that my YYERROR_VERBOSE
dnl code tweaks changed in bison 2.1, and I haven't taken the
dnl time to track it down, so skip this test for now.
