SunOS 4.1 & KSH-88d (

[Doug Kingston]

I believe that I have found the necessary changes to make KSH-88d compile
an run on SunOS 4.1.  My only question at this point is whether we should
be doing a setsid system call on SunOS 4.1.

Here are the changes:

a) in install/pgroup.c, change both occurences of "#ifdef getpgrp"
   to "#ifdef setpgrp".

b) modify install/config to accomodate the changes in the header
   files (ANSI style function prototypes and setpgid support).
