Changes for Irix 4.0, tested this time:
* s/irix4-0.h: Get rid of our fake definitions for setpgrp and getpgrp. * callproc.c (Fcall_process): Go ahead and use the USG calling convention for setpgrp. * ymakefile (pre-crt0.o): Add rule for this. Perhaps it will help separate-source-directory compilation. * emacs.c (shut_down_emacs): Some USG systems #define EMACS_HAVE_TTY_PGRP; call getpgrp as appropriate for such systems. * sysdep.c (sys_suspend): Call getpgrp as appropriate for USG and non-USG. * process.c [IRIX] (create_process): Don't put child in process group zero before opening the tty; Irix is like USG in this regard.
