Hah.  I *wish* you could have FTP'd _anything_ from robobar.  We don't
have Internet access (sob!) You must have got it from one of our friends...

Hm.. did you remember to remove alloca.o from the link command line in the
Makefile ? it would have saved you another 30 whole bytes !! (:-)

I don't think you need much.  I recall just enabling one of the HPUX
defines which used 0 instead of the except_fd's to get it to work
(having defined HAVE_SELECT as well, of course).  No guarantees, this
was a while back.

Then I took it out again because it doesn't work under SXT's and I'd rather
have job control than select() right at the moment.  It might be nice to
be able to select which select() to use at run time, so

	if (running under an sxt) {
		use emacs fake select()
	} else {
		use real select()
	}

but that was more than a one line hack, so I haven't got round to it.

(Anyone at SCO interested in making sxt's work with select() ? :-) That
 would be the _real_ solution, of course.)

Defining HAVE_PTYS was really useful though.  The only use I have for
EMACS is as a window system for GDB -- I'm from the vi camp -- and M-x
gdb is pretty hopeless without HAVE_PTYS.  Doesn't work under 2.3.1
though.
