Hyperactive Directory Administrator does not work in 7.8

Bills Hyperactive Directory Administrator (http://hww3.riverweb.com/ hdadmin/#download) that hasn't been updated since 2002 does not work with 7.8, or 7.6 for that matter. The web page states it's been tested with 7.4.20, but even trying to run it in compatibility mode gives the same resolver problem:

% ~/bin/pike77/bin/pike -M. -V 7.4.20 hdadmin.pike
util.pike:33:Trying to inherit placeholder program (resolver problem).
hdadmin.pike:31:Error finding program
hdadmin.pike:31:Illegal program pointer.

Granted, it will probably fail due to lack of GTK on all modern systems, but that is another problem.

Caveat emptor: The 7.7 I'm using is slightly old and I haven't tried with 7.4. Just jotting it down for future study.
