coreutils 5.0 on Tru64 Unix

[Tony Leneis]

        Tru64 Unix declares __sys_siglist in signal.h.  It works just like
_sys_siglist and sys_siglist on other systems.  I'm not sure what the
rationale was behind it, but it would be nice if configure could detect
this and use the same work-around in kill.c that _sys_siglist does.  (It's
necessary because Tru64 Unix doesn't have strsignal().)

        Assuming you want to follow the same naming scheme, I guess config.h
would set HAVE_DECL___SYS_SIGLIST to indicate there's a __sys_siglist.  Here
is the patch for src/kill.c:

--- kill.c      2002-09-02 00:29:44.000000000 -0700
+++ patchedkill.c       2003-04-04 22:20:43.000000000 -0800

I'm not an autoconf person, but here's a test program for __sig_siglist:

/* end confdefs.h.  */
$ac_includes_default
int
main ()
{
#ifndef __sys_siglist
  char *p = (char *) __sys_siglist;
#endif

  ;
  return 0;
}

        There's one other thing: I'm not sure why, but GNU Make 3.80 seems
to choke on the coreutils 5.0 distribution (mostly it denies that various
targets, such as check, exist.)  I'll have to investigate the problem further.
