It seems incorrect to me. AC_MISSING_PROG is a macro performing a task (i.e., an instruction), while AC_CHECK_PROGS wants a value as $4 (i.e., an expression). The point of missing is having the right thing happen even if the program is missing, so don't bother looking for a Yacc, require Bison: AM_MISSING_PROG([YACC], [bison -y])
