+        Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
+        This removes code that has been obsolete since around 1990.
+        * callproc.c (Fcall_process):
+        * emacs.c (main):
+        * process.c (create_process):
+        * term.c (dissociate_if_controlling_tty):
+        Assume setsid exists.
+        * callproc.c (child_setup): Assume setpgid exists and behaves as
+        per POSIX.1-1988 or later.
+        * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
+        * emacs.c (shut_down_emacs):
+        * sysdep.c (sys_suspend, init_foreground_group):
+        Assume getpgrp behaves as per POSIX.1-1998 or later.
+        * msdos.c (setpgrp): Remove.
+        (tcgetpgrp, setpgid, setsid): New functions.
+        * systty.h (EMACS_GETPGRP): Remove.  All callers now use getpgrp.
+        * term.c (no_controlling_tty): Remove; unused.
+        * w32proc.c (setpgrp): Remove.
+        (setsid, tcgetpgrp): New functions.
+
         Simplify by assuming __fpending.
         * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
         (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
