building rc on QNX4

[Sam Roberts <sroberts@uniserve.com>]

rc looks really good to me, so I built it over the weekend, and
I'm starting to use it. I think I've seen a few problems, but I'll
play some more and see what I can turn up, in the meantime, here's
what I had to do to get it to build:

- it has setpgid(), but not setpgrp();
- it also has a utoa in <stdlib.h>, but not with the same args;
- and it's va_list isn't an lvalue.

So, are these patches accpetable? QNX's default bastardized ksh
is ok for interactive use, but not great for programming, and
I don't think I have to bash bash on the rc mailing list... 
(sorry, I couldn't resist ;-)

Also, there's a few things I've always figured should be easy,
like piping fds other than stdout->stdin, that are under rc.

Oh, and QNX also lacks a groff tex formatting system... do you
think you could distribute a pre-processed rc.1 as rc.man, so
it could be read by less? And how about postscript as well
(groff -man rc.1>rc.ps)?

I found a Linux box to format rc.1 on, but...

Anyhow, I'm sure I'll have more questions as I play.

So far so good, and thanks a bunch!
Sam
