1.
File: load.c
Function: load_average

In addition to the patch already made from 3.54 the test on the lseek
call has to change from

  if (lseek (kmem, offset, 0) < 0L)

to

  if (lseek (kmem, offset, 0) == (long)-1)


In my case the address of "_avenrun" (offset value) happens to be
2148358396 and the lseek calls returns it as a signed value
(-2146608900).  So the value is less than 0 but the lseek call didn't
fail at all. It seems (Unix manuals, X/Open Portability Guide 3
[xpg3]) that -1 is the only value returned when lseek fails.

2.
File: job.c

The macro WCOREDUMP is not defined in <sys/wait.h> (because it is not
present in xpg3, Posix, I guess). So I added the right Ultrix
definition when WTERMSIG is defined:

#ifdef  WTERMSIG
#define WAIT_T int
#define WCOREDUMP(x)    (((union wait *)&(x))->w_coredump)
#else

....
