OK, but the referenced patch doesn't do that. It does something like this instead. Why is this a problem with those other shells? #!/bin/sh ENV=sdf readonly ENV as_unset=unset for as_var in ENV MAIL MAILPATH do ($as_unset $as_var) >/dev/null 2>&1 && $as_unset $as_var done echo "hello" _______________________________________________ Autoconf mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/autoconf
