* callproc.c (setpgrp): Remove macro, as we now use setpgid and it is configured in conf_post.h. (Fcall_process): Don't invoke both setsid and setpgid; the former is enough, if it exists. * callproc.c (Fcall_process, child_setup): * process.c (create_process): Use setpgid. * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes for the real thing. * dispnew.c (init_display): Initialize the foreground group if we are running a tty display. * emacs.c (main): Do not worry about setpgrp; init_display does it now. * lisp.h (init_foreground_group): New decl. * sysdep.c (inherited_pgroup): New static var. (init_foreground_group, tcsetpgrp_without_stopping) (narrow_foreground_group, widen_foreground_group): New functions. (init_sys_modes): Narrow foreground group. (reset_sys_modes): Widen foreground group. Fixes: debbugs:12697
