There seems to be a requirement to check their web site for
any "notices". I can't make out if this is a requirement on
the person packaging the stuff, or on the end user (but since
it's in the *source code* agreement, I assume it's only for the
person making the package).
Also, any patch must be sent to AT&T.
This seems a fair bit less liberal than the GPL...

Yes I know, the thing builds even on Cygwin system (what I'm
stuck with at work) and I've built it on my NetBSD/i386 and
NetBSD/sparc systems at home as well. That's not the point.

Not being able to vi-tabcomplete in ksh93 sucks, but pdksh
hasn't been updated for a very long time now (last patch was in
Jan 2001, before the release of the ksh93 source from AT&T), and
the ksh88 that it emulates sucks even more than the odd quirk in
ksh93 when you know what you're missing from ksh93...

I'll think a bit more and see what's happening with pdksh (I'll
query the maintainer). I might settle on using it as I am
now, on my own systems (which is a pity since it's a wonderful
