parse.pl and check_rules.pl used "no warnings 'uninitialized'", which doesn't seem like it measures up to current project standards. Removing that shows that it was hiding various places that accessed off the end of an array, which are easily protected by minor logic adjustments. There's no change in the script results. While here, improve the Makefile rule that invokes these scripts. It neglected to depend on check_rules.pl, so that editing that file didn't result in re-running the check; and it ran check_rules.pl after building preproc.y, so that if check_rules.pl did fail the next "make" attempt would just bypass it. check_rules.pl failures are sufficiently un-heard-of that I don't feel a need to back-patch this.
