Right, and you've even included the licence, so I've committed it as it is.
Thanks.

I think the answer here is probably --disable-dynamic.  It's going back a
while, but I have a suspicion dynamic linking has always been problematic
on SunOS 4.  It might be fixable if anyone thought it worth while and had
the time and facilities.

For the specific problem, on some older systems an underscore needed to be
added by hand to entry points when fetching them with dlsym().  It looks
like this is some variant of that problem (although dlsym() isn't directly
involved).  Again, it's going back a bit and I'm not sure how this was
supposed to pan out.

Job control definitely worked once on 4.1.x because I used to use it all
the time about 15(!) years ago, although I think that was in the age before
vim.  It's likely to need some poking around with a suitable system, unless
it awakes some memory of Bart's.

It might be worth trying "ttyctl -f" before calling vim the first time in
case it's monkeying with terminal settings.  I don't hold out much hope,
but it's at least a very quick test.
