Depends on the configure.in author; it only checks what it's told
to check =) For those who want to modify the autoconf script to make
this happen, you want to use AC_PROG_YACC which sets the YACC variable
(i.e. put @YACC@ in Makefile.in). If it uses features like -p that old
yacc doesn't support you'll need to do something like
AC_PROG_YACC
test "$YACC" = "yacc" && AC_MSG_ERROR("need bison or byacc")
