dnl byacc on FreeBSD 4.3 gives weird parsing problems.

dnl byacc on FreeBSD 4.10 seems fine.

dnl The bap -d argument only works with bison, so enable it

dnl if we're using bison.

dnl if test "$ac_cv_prog_YACC" = "bison -y"; then

dnl doesn't seem to work with bison 2.1

dnl AC_DEFINE(YYERROR_VERBOSE, 1, [define if we're using bison])
