Okay, all the rc(5) scripts work flawlessly! :) All my user scripts work
flawlessly, GNU configure works flawlessly, and PERL5's config scripts
work fine too. As a bonus, pdksh has better PS[1-4] support, and
co-processes (blah |&). I'll be using pdksh as /bin/sh from now on, and if
I run into any trouble, I'll let you know.
