OK, I just posted something to gdb-announce.

These three should be identical.
Not quite. i386-*-elf* uses a register numbering scheme for stabs
(stabs-in-ELF to be precise) that differs from traditional stabs used
for a.out and COFF.

Can this go? I think it is the old old Novell thing.
Right now it's only supported as a target, and it was really trivial
to add. So I'll keep it.

ChrisF would like the PE deleted! It's been bug reported.
Ah, well, it's basically identical to i386-*-aout* and i386-*-coff*.
The only "support" is the line in configure.tgt. I'll leave it to
Chris to decide what to do with it.

What is this machine?

I think this can go (or at least an attempt made).
I'll leave it alone for now.

Obsoleting os9kread is on the to do list as well.
Yup!

Have fun!
I'll probably start making a real mess next weekend ;-). I hope it'll
be acceptable that some targets will be broken for a few days. I
don't think I can keep things compiling without resorting to one large
mega-patch.
