[BUG] priv-set on aix6.1

[Gary V. Vaughan]

I get a compilation failure in coreutils with the priv-set module
which correctly detects a getppriv() function, but then tries to use
it by including a non-existant <priv.h> header.

From priv-set.h:

  #if HAVE_GETPPRIV

  # include <priv.h>

From the aix manual page for getppriv:

  Purpose

       Gets a privilege set associated with a process.

  Library

       Security Library (libc.a)

  Syntax

       #include <sys/types.h>
       #include <sys/priv.h>
       int getppriv(pid, which, privset, privsize)
       pid_t pid;
       int which;
       privg_t *privset;
       int privset;

I guess the solution is to add checks for <priv.h>, <sys/priv.h> 
headers and change priv-set.h to read as follows (or similar):

  #if HAVE_GETPPRIV
  # if HAVE_PRIV_H
  #   include <priv.h>
  # else
  #   if HAVE_SYS_TYPES_H
  #     include <sys/types.h>
  #   endif
  #   if HAVE_SYS_PRIV_H
  #     include <sys/priv.h>
  #   endif
  # endif
  ...
