This code fails too if the user has compiled his own binary and runs
it from ~/bin/ksh.

Since we are exchanging tips now I'll give you mine to. I put this in
/etc/profile to load /etc/kshrc and $HOME/.kshrc if exists

if (echo $0|grep -q ksh)
    ... ksh stuff

Still can't tell the difference between pdksh and ksh.

All of this hacks are only needed because of ksh's lack of a "real" rc

To make things even worse, there's no way that I know of to load
defaults for non-interactive non-logged-in shells. The retarded $ENV
construct assumes that the user is logged in when he starts a
non-interactive shell.

But many a script is run from cron or at and there is no way to force
the loading of any defaults or even a PATH.

All of that can be fixed, though. ksh is basically OK
I guess I have to write that maintainer now...
